Question

Which equation could have been used to create this graph?












A.

y = 3x + 3








B.

y = 3x








C.

y = 30x








D.

y = 3x + 1

Answer 1

B.) y=3x
The slope of a given line is defined by y=mx+b, where b is the y-intercept (the point at which the line crosses the y-axis) and m is the slope (rise/run). We see that the y-intercept is 0 (because the line hits the y-axis at 0) and the slope is 3 (rise=3 and run=1, so 3/1=3).
