What is an equation of the line that passes through the points (4,-5) and (-2,7)
Korvikt [17]

Answer:

y = -2x + 3

Step-by-step explanation:

-2

The slope is -2.

To find the y-intercept, you need to plug the coordinates into the equation.

y = -2x + b

7 = -2(-2) + b

7 = 4 + b

3 = b

y = -2x + 3
