Answer:
y-b+am/m
Step-by-step explanation:
y-b=m(x-a)
y-b=MX-ma
mx=y-b+ma
x=y-b+ma/m
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
Answer:
Quadratic because the y values go up and then down. None of the other options can do that.
You could buy 135 MP3 songs.
($304.25 - $149 = $155.25 | $155.25 / 1.15 = 135)
1. 15-x
2. 4y
These are algebraic expressions for both.
