The equation is y = 4 + x.
\The equation is in slope-intercept form.
\First find the y-intercept.
\The y-intercept is the value of y, when x = 0.
\y = 4 + 0 (Substitute: x = 0)
\y = 4 (Additive identity property: 4 + 0 = 4)
\The co-ordinate point is (0, 4)
Next find the x-intercept.
\The x-intercept is the value of x, when y = 0.
\0 = 4 + x (Substitute: y = 0)
\04 = 4 + x
4 (Subtract 4 from each side)
04 = 4
4 + x (Commutative property: a + b = b + a)
04 = x (Additive inverse property: 4
4 = 0)
x = 4 (Additive identity property: 0
4 =
4)
The co-ordinate point is (4, 0)
