you want the form : y=mx+b
so organizing into this form:
2y = 4x - 24
y = 2x - 12
m = 2
b = -12
so D
so organizing into this form:
2y = 4x - 24
y = 2x - 12
m = 2
b = -12
so D

ans is d
m=-(x coeficient)/(y coeficient)=>-4/-2=2
y intercept means x=0 => 4(0)-2y=24 =>-2y=24 =.y=-12
.`. m=2 & y=-12
m=-(x coeficient)/(y coeficient)=>-4/-2=2
y intercept means x=0 => 4(0)-2y=24 =>-2y=24 =.y=-12
.`. m=2 & y=-12

I would change the form of the equation to y=
4x - 2y = 24
-2y = 24 - 4x
y = 2x - 12
From this the slope is 2 and the y-intercept is -12
d)
4x - 2y = 24
-2y = 24 - 4x
y = 2x - 12
From this the slope is 2 and the y-intercept is -12
d)

Look at Equation of a Straight Line
y = mx + c
so change you equation in the above form to give
y=2x-12
hence m = 2 and when x=0, y = -12
y = mx + c
so change you equation in the above form to give
y=2x-12
hence m = 2 and when x=0, y = -12

It's d. You have to subtract 4x then divide by -2.

You should probably pay more attention in class...
