Answer:
at t=0 the car has moved 0 feet, also you know it has a constant speed so you get the points:
P1:(0,0) therefore you know b, the y-intercept=0
P2:(8,840)
insert P2 into y=mx+b
840=8m+0
840/8=m
105=m
so the result is:
y=105x=105t=f(t)=d

Hello!

as a fraction.
0.344 = 0.344/1
The 4 is in the thousandths place. Multiply both the numerator and the denominator by 1000.
0.344 × 1000 = 344
1 × 1000 = 1000
This gives us: 344/1000
It's fraction form can be reduced. Simply divide both the numerator and the denominator by 8:
344 ÷ 8 = 43
1000 ÷ 8 = 125
We are given a line passes through the point (-2,5). The slope should have been given as well. Assuming that the slope is 2, we can determine the values of x and y for the points A and B.
The formula for the slope is
m = (y2 - y1)/(x2 - x1)
The slope between (-2,5) and A(x,3) is
2 = (3 - 5) / (x - (-2))
Solve for x
Use the same approach for the points (-2,5) and B(-2,y) to solve for y.
