Jacks car used 18 gallons of gasoline to go 468 miles. at that rate, how many gallons would be used to go 754 miles?

A

Step-by-step explanation: So, first of all, this is a linear graph, which is represented by the equation y = mx + b.

b = y-intercept. The y-intercept is the point in which the line crosses the y axis. Assuming this graph has units that go up by 1, the y- intercept for this line is 2, which eliminates choices B and C.

This graph is going down, which means it is negative, so the format should be -mx + b, which is answer choice A. Hope this helps! :)
