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
Amplitude: 1/4 (= |a|)
Frequency: 1/2 (= |b|)
Period: 4pi (= 2pi/|b|)
Alicia: 43 miles/hour
Trish: 46 miles/hour
so Alicia drives at a slower rate
Answer:
Assuming you want an equation, y = -4/3x - 1
Step-by-step explanation:
Formula is y = mx + b
m = slope= -4/3
b = y-intercept = -1
