How do you graph #7x-2y=-14# using intercepts?
Plot the points,
2 Points is the minimum number of points needed to draw a line.
The intercepts on the axes are two useful points.
All points on the x-axis have the y value = 0
All points on the y-axis have the x value = 0
To find the x-intercept. make y=0.
To find the y-intercept, make x =0
For x-int: Make y=0:
For y-int: Make x=0:
So plot the points,
Draw the line through them.
