Slope intercept form: y=mx+b, m=slope=rise/run, b=y-intercept when x=0
Line is decreasing from left to right, the slope is negative.
From point (2,-4) to (-3,1) is a rise 6 and run left 6
Slope=-6/6=-1
Look on the line for x=0 to find y-intercept, y-intercept is -2
Equation of the line is:
y=mx+b
y=-x-2
