Answer:
The answer to your question is 2 or (2, 0)
Step-by-step explanation:
Data
slope = m = 4
y-intercept = -8
Process
1.- Write the equation of the line in the slope y-intercept
y = mx + b
In this equation:
m = slope
b = y-intercept
-Substitution
y = 4x - 8
2.- To find the x-intercept, consider that y = 0 and solve for x.
0 = 4x - 8
4x = 8
x = 8/4
x = 2 or (2, 0)
I believe they are perpendicular because their slopes are negative reciprocals of each other.
In y=mx+b, m is the slope.
So the slopes are 4 and -1/4, so perpendicular.
