Y = mx + b
where m = slope and b = y-intercept
You're already given that the slope is 5/2, so put that for m
y = 5/2x + b
To find b, use the ordered pair you're given (-4, -3) and plug -4 for x and -3 for y and solve for b.
-3 = 5/2 * -4 + b
-3 = -10 + b
7 = b
y = 5/2x + 7

A-b=21
5a-2b=18
We can use substitution here. Take the first equation and solve for A. (Picking this one because it's easy)
a = 21+b
Plugin to the second equation:5(21+b)-2b=18
Simplify: 105 + 5b - 2b = 18
Simplify: 105 + 3b = 18
Subtract both sides: 3b = 18-105
Simplify: 3b = -87
Divide: b = -29
Plug back into the first: a=21+b
a = 21 - 29
a = -8
Option D
Answer:
h = 22 for Rachel
Step-by-step explanation:
20 + h = 42
h = 42 - 20
h = 22
