Question

Please help me with the graphing. I struggle with graphing.

Answer 1

In order to calculate the slope, let's put the equation in the slope-intercept form:

$y=mx+b$

Where m is the slope and b is the y-intercept.

So we have:

$\begin{gathered} -15x+3y=45 \\ -5x+y=15 \\ y=5x+15 \end{gathered}$

So the slope is 5 and the y-intercept is (0, 15).

To find the x-intercept, let's use y = 0 in the equation:

$\begin{gathered} 0=5x+15_{} \\ 5x=-15 \\ x=-3 \end{gathered}$

So the x-intercept is (-3, 0).
