Answer:
Expression for Larry will be;
Expression for Zach will be;
Step-by-step explanation:
Given:
Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.
Amount for each flower bed he weeds = $7
Number of flower bed he weeds = 3
Total amount he gets for 3 flower bed he weeds =
Amount earn to edge a yard = Y
Total amount Larry will earn = $21 + $Y
Now Zach will get $25 to clean a garage and Y dollars to wash a car.
Amount earned to clean garage = $25
Amount earned to wash as car = $Y
Total Amount Zach will earn = $25 + $Y
The Both have to make X dollars to meet their goals.
Expression for Larry will be;

Answer:
1) y=⅚x -2⅓
2) y=8/3x -5
Step-by-step explanation:
<u>Point-slope form:</u>
y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient.
Gradient of given line=
Thus, m=⅚
Susbt. m=⅚ into the equation,
y= ⅚x +c
Since the line passes through the point (4, 1), (4, 1) must satisfy the equation. Thus, substitute (4, 1) into the equation to find c.
When x=4, y=1,
1= ⅚(4) +c
Thus the equation of the line is .
The gradients of perpendicular lines= -1.
Gradient of given line= -⅜
-⅜(gradient of line)= -1
gradient of line
= -1 ÷ (-⅜)
= -1 ×(-8/3)
=
When x=3, y=3,
Thus the equation of the line is .
