5 (2k - 8 ) - 15 = -25
how do I solve this?

3=k

5(2k-8)-15=-2510k-40-15=-2510k-55=-2510k=-25+5510k=3030÷103=k

Without graphing, we can tell that a solution is going to be (0,-1). This is because in slope intercept form, y=mx+b, the “b” is our “y intercept.”
What this means is: the point on the graph that the given line goes through when x=0. In this case, “b” is -1, so the line will go through (0,-1).
