I bet nobody ain’t going to answer this question

The graph passes through (2,35) and (4,70) and the slope represents the train traveling at a rate of 17.5 miles every hour.

To check if a point is on a line, plug in the coordinates of the point for x and y. The point is on the line of both sides equal each other. For example, let’s check if (0,0) is a point on the line.

y = 17.5x
0 = 17.5(0)
0 = 0
so (0,0) is on the graph because 0 equals 0.

Check for (17.5, 1)
1 = 17.5(17.5)
1 = 306.25
1 does not equal 306.25 so (17.5, 1) is not on the line.

Check for (2,35)
35 = 17.5(2)
35 = 35
So (2,35) is on the line

Check for (4,70)
70 = 17.5(4)
70 = 70

x represents the amount of hours the train has been traveling. y represents the amount of miles the train travelled. So on the point (2,35), in 2 hours the train travelled 35 miles. This relates to the slope as you multiply the number of hours by the slope because that is how many miles the train travelled per hour.

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
