Answer:
X-intercept is (-3,0)
Y-intercept is (0,-7)
Step-by-step explanation:
0 is the answer to the question.
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
Step-by-step explanation:
-2x=30-120
-2x = -90
=x = -90/-2
=x = +45
