Wirte an equation for (-2, -5), (-6,9)
olchik [2.2K]

Answer:

y = -3.5x - 12

Step-by-step explanation:

Find the slope with rise over run: (y2 - y1) / (x2 - x1)

Plug in the points:

(9 + 5) / (-6 + 2)

14/-4

= -3.5

Then, plug this and a point into the equation y = mx + b to find b:

y = mx + b

9 = -3.5(-6) + b

9 = 21 + b

-12 = b

Then, plug this and the slope into the equation again:

y = mx + b

y = -3.5x - 12 will be the equation
