Answer:
The slope formula is m=(y2-y1)/(x2-x1).
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
Answer:
a. -2
b. y = -2x + 4
Step-by-step explanation:
using (-9, 10) and (-3, -2)
Slope m = (y2-y1)/(x2-x1)
m = (-2 - 10)/(-3 - -9)
m = -12/6 = -2
Slope-intercept: y = mx + b
using (-3, -2)
-2 = -2(-3) + b
-2 = 6 + b
b = 4
y = -2x + 4
