slope int. form is y=mx+b
y is the y intercept or the point on the y axis, m is slope, and b is a y intercept
first find your slope by using the formula y2-y1 / x2 -x1
(-2-3)/[3-(-2)] = -5/5= -1
your slope is -1
now using one of your y intercepts provided, you can plug either y intercept in and get either:
y= -x + 3
OR
y=-x - 2
hope this helped :))
