Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)

Answers

Answer 1

Answer: y = -3.5x - 4.5

suppose: the equation of the line is y = ax + b ( a ≠ 0 )

because the line passes through (-2;2.5) => 2.5 = -2a + b

the line passes though (0;-4.5) => -4.5 = b

=> b = -4.5

   2.5 = -2a + b

=> a = -3.5

    b = -4.5

=> the equation of the line is y = -3.5x - 4.5

Step-by-step explanation:

Answer 2
The equation Of the line is y =-3.5x-4.5

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)  

x₁ - x coordinate y₁ - y coordinate m - slope

Standard Form: Ax + By = C

Step-by-step explanation:

Step 1: Define

Point-Slope Form:   y + 5 = -10(x - 1)

Step 2: Find Standard Form

Distribute -10:                              y + 5 = -10x + 10Add 10x on both sides:               10x + y + 5 = 10Subtract 5 on both sides:           10x + y = 5
