The equation is .
To find the y-intercept, and x = 0.
\ (Substitute x = 0)
(Apply zero product property:
)
(Apply addititve identity property: 0 + 1 = 1)
The coordinate point is (0, 4).
\y-intercept is 4, So graph is (0, 4).
To find the x-intercept, and y = 0.
\ (Substitute y = 0)
Apply subtraction property of equality: If a = b then a b = b
a.
(Subtract 4 from each side)
(Apply additive inverse property:
)
(Apply additive identity property:
)
Apply multiplication property of equality: If a = b then .
(Multiply each side by 2)
(Cancel common terms)
(Multiply:
)
The coordinate point is .
The above eqaution comparing the slope-intercept form , Then m =
, b = 4.
1) y-intercept is 4, So graph is (0, 4).
\2) From (0, 4), move up 1 unit and right 2 units.
\3) Draw a dot.
\4) Draw a line through the points.
To graph the equation .
The solution of the graph eqution .
