Question 82415
y=-2x+1
This is in slope intercept form with a slope of -2 and a y intercept of 1.
Mark a point on the y axis at 1. As the gradient is -2 move 1 unit to the right and two units down (down because the gradient is negative) then place a second point. Join the two points with a straight line.
