Starting at the same point at the same time, samuel and heather rode their bikes in the same direction. samuel traveled 3km/h faster than heather. after 3.5h samuel stopped for a half-hour break, but heather kept going. at the end of the break, heather was 8km ahead of samuel. how fast was each going?

(this is a speed, distance, time question)

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

2425

step-by-step explanation:

it is 10.6 according to my calculations
