Answer:
Step-by-step explanation:
Find the slope by doing rise/run
-2/3
Find the y intercept: (0, -2)
The equation will be y = -x - 2
Probably the subsitution method
y=1/2x
subsitute that fr y
2x+3(1/2x)=28
2x+3/2x=28
times 2 both sides
4x+3x=56
7x=56
divide by 7 both sides
x=8
sub back
y=1/2x
y=1/2(8)
y=4
(x,y)
(8,4)
168/3=56. 56 miles per hour.
