Graph y=-8x
Problem
Solution
Identify the type of equation. This is a linear equation in the form
y=m*x+b wherem=−8 andb=0 Determine the y-intercept. Since
b=0 the line passes through the origin at the point(0,0) Analyze the slope. The slope
m=−8 indicates that for every1 unit the graph moves to the right, it moves down8 units.Calculate a second point. Substitute
x=1 into the equation to findy=−8*(1)=−8 giving the point(1,−8) Plot the points
(0,0) and(1,−8) on a coordinate plane and draw a straight line through them to represent the function.
