Answer:
The slope is 1/2 and the y intercept is 7/4
Step-by-step explanation:
2x-4y+7=0
To find the slope, we need to put the equation in slope intercept form
y = mx+b
So we need to solve for y
Subtract 2x from each side
2x-2x-4y+7=0-2x
-4y +7 = -2x
Subtract -7
-4y+7-7 = -2x-7
-4y = -2x-7
Divide by -4
-4y/-4 = -2x/-4 -7/-4
y = 1/2 x +7/4
The slope is 1/2 and the y intercept is 7/4
1200/8 = x/3
150 = x/3
150 * 3 = x
450 = x

1 1/6 hrs.....1 hr = 60 minutes......1/6 hr = 1/6(60) = 60/6 = 10 minutes....therefore, 1 1/6 hrs = 70 minutes
(7/8) / 70 = x / 1....7/8 of the wall to 70 minutes = x wall in 1 minute
cross multiply
(70)(x) = (7/8)(1)
70x = 7/8
x = (7/8) / 70
x = 7/8 * 1/70
x = 7 / 560 reduces to 1/80 <== she paints 1/80 of the wall in 1 minute
