Find the y-intercept and the x-intercept of:
-2x%2By+=+13
The y-intercept occurs when x = 0, so substitute x = 0 and solve for y.
-2%280%29%2By+=+13
y+=+13
The y-intercept is at (0, 13)
The x-intercept occurs when y = 0, so substitute y = 0 and solve for x.
-2x%2B0+=+13
-2x+=+13 Divide both sides by -2.
x+=+13%2F-2
x+=+-%286.5%29
The x-intercept is at (-6.5, 0)
