Question

Find the intercepts of the equation y=2x-1 by plotting points.

To plot this would I just plot 2,0 and then go down 1?

Answer 1

To find the x-intercept, let y=0 and solve for x.

Therefore,
0=2x-1 ---> x=1/2

To find the y-intercept, let x=0 instead.

y=2(0)-1 ---> y=-1

From here, you plot the points (1/2,0) and (0,-1) on the graph.
