The straight line PQ with a slope of -2 passing through point (-3, 10). Find the y-intercept of the straight line PQ .
The slope intercept equation is in the form y=mx+b. We already know the slope so we have y=-2x+b. Then we plug in the point (-3, 10) to find b, the y-intercept.
So the y intercept of line PQ is (0, 4).
