You're looking for a line with the formula y= mx+ b , in which m= slope and b= y intercept.
First, use the slope formula with your two points to find the slope.
That is "m."
Next, plug one of your points, such as (-5,0) into the equation.
0= -5m + b
You should have m already from the slope formula. You then solve for b.
Finally, you put it all together.
y= mx+ b
Alternately, to find b you can use the formula y1-y= m(x-x1), called the point-slope formula.
