Find the equation of a line containing the given points. Write the equation in slope-intercept form.

y = ?

Answers

Answer:

y = x + 1

Step-by-step explanation:

(2,3)  (-2, -1)

line equation y - y1 = m (x - x1)

m = (-1 -3) / (-2 - 2)

= -4 / -4 = 1

y - 3 = 1 * (x - 2)

y = x -2 +3

y = x + 1

Answer:

y = 1x+1

Step-by-step explanation:

Slope-intercept form is: y=mx+b

In order to find the slope, or "m" in this formula with two given points, use the slope formula for two coordinates: m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].  In this formula, y2 is the second coordinate's y value, y1 is the first coordinate's y-value, and likewise x2 is the second coordinate's x value, x1 is the first coordinate's x-value.

In this problem specifically, we were given coordinates (2,3) and (-2,-1).

This is how those above values would line up:

y2 = -1

x2 = -2

y1 = 3

x1 = 2

Once this is plugged into the formula it becomes [tex]\frac{-1-3}{-2-2}[/tex] , which simplifies to a slope (m) of 1.  

____________________________________________________________

Next to find the y-intercept, or "b" we simply need to plug in a coordinate's values into the slope-intercept form, and I chose (2,3) for simplicity's sake.

This would become (3) = 1(2) + b. Then just solve for b using algebra, which results in a b value of 1.  

The answer is y= 1x +1 which can alternatively be written as y=x+1

You have 6 pints of glaze. It takes ⅞ of a pint to glaze a bowl and 9/16 of a pint to glaze a plate

Answers

Your question is Incomplete

Is Your question this?

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.

A. How many bowls could you glaze

B. How many plates can you glaze

C. How much glaze will be left over?

If it is the Answer is below.

(If it not please tell me)

Answer/Step-by-step explanation:

Given:

6 Pints of glaze

takes 7/8 of pint to glaze a bowl

9/16 of a pint to glaze a plate

Part A) How many bowls could you glaze?

You have 6 pints of glaze. It takes 7/8  of a pint to glaze a bowl

so

To find the number of bowls divide 6 by 7/8

= 48/7 = 6.86 bowls

Therefore the answer to part A is equal to 6 bowls.

=================================================================

Part B) How many plates can you glaze?

You have 6 pints of glaze. It takes 9/16  of a pint to glaze a plate

so

To find the number of plates divide 6 by 9/16

=96/2 = 10.67 plates

Therefore the answer to part B is equal to 10 plates.

=================================================================

Part C) How much glaze will be left over?

[tex]Part A =6-6*\frac{7}{8} =6-\frac{42}{8} =\frac{48}{8} = \frac{42}{8}=\frac{3}{4}[/tex] pint of glazes left

[tex]Part B=6-10*\frac{9}{16} =6-\frac{45}{8} =\frac{48}{8} -\frac{45}{8} =\frac{3}{8}[/tex] pint of glazes left

Maybe b. Or c but I’m not sure if it’s a problem with the problem with this problem lol it’s still available for sure

Answers

Answer:

Yes

Step-by-step explanation:

0.7988-0.5= 0.7488

0.7988+0.5= 1.2988

0.7925 lies between these values.

A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental?

A. 75.00 + 160.00x = 760.00
B. 75.00x – 160.00 = 760.00
C. 75.00 – 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

Answers

Answer:

D. 75.00x+160.00=760.00

Answer:

Letter D.

Step-by-step explanation:

Since I believe we are trying to decipher the number of days the car must be rented if they want to spend exactly 760.00$, you must multiply the number of days by the rental price and add the fee. So, let’s test it out!

160.00 = 760.00

-160.00 -160.00 = 600.00

and then,

75.00x = 600.00

———. ———-

75.00 75.00 = 8
