Answer:
7. x = -4/3 x + 8
8. see graph
Explanation:
7. 4x+3y = 24
We need to get this in slope intercept form ( y= mx+b)
Subtract 4x from each side
4x-4x+3y = -4x+24
3x = -4x+24
Divide each side by 3
3x/3 = -4x/3 +24/3
x = -4/3 x + 8
The slope is -4/3 and the y intercept is 8
8. 8x -2y =4
We need to get it in slope intercept form ( y= mx+b)
Subtract 8x from each side
8x-8x -2y = -8x+4
-2y = -8x+4
Divide by -2
-2y/-2 = -8x/-2 +4/-2
y = 4x-2
The slope is 4 and the y intercept is -2
Start at the origin and go down 2 units. This is the y intercept of (0,-2) Then the slope is 4 (4/1) Go up 4 and to the right 1. Plot a point. Go up 4 and to the right 1. Connect the points and that is the line
