Hello there!
We are given that a line has a slope of 7 and a y-intercept of -15.
Now, to write this equation in slope-intercept form, we should remember what slope-intercept form looks like.
It looks like so:
y=mx+b
Where m is the slope and b is the y-intercept.
In this case, m is 7 and b is -15.
Therefore, the equation is:
y=7x-15
Hope it helps.

Good luck.
