Question

On a piece of paper, graph y=4x-2. then determine which answer matches the graph you drew?

Answer 1

Because this equation is in slope-intercept form, we can tell exactly how it will look by checking out 3 key points.

Leading coefficient: negative, or positive.

In this case, the leading coefficient is positive, which means that the slope will be going from bottom left to upper right.

Leading coefficient = slope

In this case, the slope is 4, or 4/1, so it will be at a steep incline.

Value of constant = y-intercept.

In this case, the y-intercept is -2, which will help us narrow down our choice.

After reviewing the three answer choices, the most likely selection will be A, as it seems to have a slope of 4, it is positive, and it has a y-intercept of -2.
