What equation represents the slope intercept form from the line below slope -3 y intercept 0,-5

I'm terrible at math any here is appreciated.

The distributive property allows you to say that 3(x − 1) = 3x −

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11
