Hi.

 

1. Rewrite the equation:

     \(-10x+2y=30\\\implies-5x+y=15\text { here we divided the entire equation by 2}\)

2. Slope intercept form is expressed as \(y=mx+b\) where m is the slope and b is the y intercept. Let's now finish up the equation and put the above into slope intercept form:

     \(-5x+y=15\\\text { add 5x to both sides}\\\implies y=15+5x\\\implies \boxed {y=5x+15}\\\text { the slope is 5 and the y-intercept is 15}\)
