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
Answer:
y = -7/2x -12
Step-by-step explanation:
The two-point form of the equation for a line is useful for this.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (9 -(-5))/(-6-(-2))(x -(-2)) -5
y = 14/-4(x +2) -5
y = -7/2x -12 . . . . the line through the given points
