Answer:
The y-intercept of this line: -4
Step-by-step explanation:
A line passes through the points (8, –1) and (–4, 2).
Slope = (-1 - 2)/(8 + 4) = -3/4
Equation in slope intercept form:
y = mx + b where m = slope and b = y-intercept
Substitute m = -3/4 into the equation to find y-intercept
y = -3/4 x + b
Plug in one of those coordinate points above to find b. In this case, I'm using (–4, 2)
y = -3/4 x + b
2= -3/4 (-4) + b
-1 = 3 + b
b = -4
