Answer:
Step-by-step explanation:
With a slope of 1 and a y intercept of -3
y = 1x - 3
y = 1(-2) - 3
y = -5
(-2, -5)
Answer:
y = mx + b
Step-by-step explanation:
Use that form to find the slope.

I'll assume the above equation is: 9 - 7x = 7 - 4(2x+3)
* do distributive multiplication
9 - 7x = 7 - 8x - 12
*move like terms
-7x + 8x = 7 - 12 - 9
* solve for x
x = 7 - 21
x = -14
To check, substitute x by its value -14
9 - 7x = 7 - 4(2x+3)
9 - 7(-14) = 7 -4[2(-14) + 3]
9 + 98 = 7 - 4(-28 +3)
107 = 7 - 4(-25)
107 = 7 + 100
107 = 107
