Can anyone help?

You can put this solution on YOUR website! Find the x and y intercepts and graph the equation plotting the equations. -3x-5y=15
To find the x-intercept, put 0 in for y:
-3x - 5y = 15
-3x - 5(0) = 15 {put 0 in for y}
-3x = 15 {multiplied -5 by 0}
x = -5 {divided both sides by -3}
x-intercept = -5
which is (-5,0) as coordinates of a point
To find the y-intercept, put 0 in for x:
-3x - 5y = 15
-3(0) - 5y = 15 {put 0 in for x}
-5y = 15 {multiplied -3 by 0}
y = -3 {divided both sides by -5}
y-intercept = -3
which is (0,-3) as coordinates of a point
To graph, put a point on (-5,0) and a point on (0,-3) and draw a line through the two points.
