Which equation does the graph below represent? y = fraction 1 over 3 + x
y = fraction 1 over 3 x
y = 3 + x
y = 3x

Y = 3x is your best bet

y = 62x + 31 (y = 2x + 1, if it is scaled by a factor of 31 for y(miles), and 1 for x(time in hours)).

Step-by-step explanation:

This equation is in the form of slope intercept: y = mx + b. Where m is the slope(rise over run/change in y over change in x), and b is the y intercept(where x is 0, and intersects the y axis)

the y intercept is 31 because this is where the line intersects the y axis, and where x is zero.

the slope is 62 since 93-31/1-0 = 62/1 = 62. or if scaled 3-1/1-0 = 2/1 = 2, and 1 for the y intercept if scaled.
