I WILL MARK AS BRAINLIEST! Write an Equation that represents the points in the table

Answers

Answer:

y = 3x + 5

Step-by-step explanation:

Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).

Substitute the information for the variables in the slope-intercept form equation.

y = mx + b

m = slopeb = y-intercept value

Answer:

y=3x +5

If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.

The above is the ‘b’ question.

We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.

In this case it would be, the mean if 2 to get 1 and the mean of 19,

The mean of 2 is,

2miles / 2 = 1 mile.

And the mean of 19 mins is,

19 mins / 2 = 9.5 mins.

Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Hope this helps you. Plz let me know if you have any doubts.

9.5 minutes because if she ran 2 miles in 19 minutes you would divide them both by 2 and 19/2=9.5
