Given the following equation of a line:


2x-5y=-12

Find the slope and the y-intercept of the line.

The slope-intercept form of a line is:


y=mx+b

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

Solving the given equation for y:


\begin{gathered} 2x-5y=-12 \\ \text{Subtract 2x} \\ -5y=-2x-12 \\ Divide\text{ by -5:} \\ y=(-2x-12)/(-5) \\ \text{Simplify:} \\ y=(2)/(5)x+(12)/(5) \end{gathered}

Comparing with the generic equation above, we find:

slope: m = 2/5

Y-intercept: b = 12/5
