Answer:
a) 7/5
your y - intercept is wrong btw, the x should always be 0 on a y-intercept so it should be (0,7)
y-7 = 7/5 (x)
Step-by-step explanation:
given the x intercept = (-5,0) and the y intercept = (0,7), we can plug these points into the slop equation
y1-y2
____ = m
x1-x2
m = (0-7)/(-5-0) = -7/-5 = 7/5
slop-intercept form is basically point slope form
y-y1 = m(x-x1)
y-7 = 7/5(x-0)
-5=-5
-12+7 = x+3
-5 = x+3
-5-3 =x
x = -8
-12+7 = -8 +3
-5 = -5
1/5+1/3=8/15 house per day
1 house=1/(8/15)=15/8 days per house working together

You do 28/100 which is 0.28
You then multiply this by 21
28/100 x 21 = 5.88
