Answer:
356
Step-by-step explanation:
Two lines are perpendicular if their slope m and m' satisfy the equation
The slope of the given line is 4, because the line is written in the slope-intercept y=mx+q, where m is the slope.
So, the perpendicular slope is
So, we want a line with slope -1/4 and passing through (-1,3). We can use the formula
for the line passing trough (a,b) with slope m:
Y+1=-8(x-2)
y+1=-8x+16
y=-8x+15
The slope would be -8
