−3x+4y=−12
Add -4y to both sides.
−3x+4y+−4y=−12+−4y
−3x=−4y−12
Divide both sides by -3.
−3x/−3 = −4y−12/−3
x=4/3y+4
solve for y.
−3x+4y=−12
Add 3x to both sides.
−3x+4y+3x=−12+3x
4y=3x−12
Divide both sides by 4.
4y/4 = 3x−12/4
y=3/4x−3
Graphing shown below.
Ответ:
y-intercept can be found when x=0
Plug in x=0 to find the y-intercept
-3(0) + 4y = -12
4y = -12
y = -3
Plug in y=0 to find the x-intercept
-3x + 4(0) = -12
-3x = -12
x = 4
The x-intercept is (4,0)
The y-intercept is (0, -3)
