Below

Explanation:

5x+2y=−1
2y=−5x−1
y=−52x−12

The general form of this equation is y=mx+b where m is the gradient or slope and b is the constant that tells you to shift up or down the graph by b units.

To find your intercepts, you need to sub either x=0 or y=0 depending on whether you are finding your y-intercept or x-intercept respectively.

When x=0,
y=−52(0)−12
y=−12
Therefore, your y-intercept is (0,−12)

When y=0,
5x+2(0)=−1
5x=−1
x=−15
Therefore, your x-intercept is (−15,0)

graph{5x+2y=-1 [-10, 10, -5, 5]}
