Two cars drive from town a to town b at constant speeds. the blue car travels 35 miles per hour and the red car travels 70 miles per hour. the blue car leaves at 10: 30. the distance between the two town is 140 what linear equation represent the red car and the blue car

We can use the formula d = rt in getting the algebraic equation for the two cars where; d = distance, r = rate, t = time.

Given:
 (blue car) = 35 miles per hour
(red car) = 70 miles per hour
distance between the two towns = 140 miles
(blue car)= no. of hours the blue car travels
(red car) = no. of hours the red car travels

Linear equation for the blue car




blue car travels 4 hours from town A to town B.

Linear equation for the red car




red car travels 2 hours from town A to town B.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
