Equation where slope = 7/2 and y-intercept is -15
1 answer:
Answer:
y = 7/2x - 15
Step-by-step explanation:
y = mx + b
if slope is 7/2, m= 7/2
y = 7/2x + b
if y-intercept is -15, y = -15, x = 0
-15 = 7/2(0) + b
b = -15
then
y = 7/2x - 15

what is b? from the first equation in the system, y + 2 = b.
Steps to solve:
7x - 10x = 15
~Simplify
-3x = 15
~Divide -3 to both sides
-3x/-3 = 15/-3
~Simplify
x = -5
