Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = 
= 
= 
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
Answer: x = 0.75
Step-by-step explanation:
3x+x - 3 =0
4x - 3=0
4x = 3
x = 0.75
Multi-step equations are equations that require more than one step to solve.
For example:
2x+6 = 10 You subtract 6 from both sides
2x= 4 Divide both sides by 2
x=2 It took 2 steps to solve for x, so it is a muti-step equation.
One step equation:
2x =6 divide 2 by both sides
x=3 It only took one step, so it is an one-step equation.

Answer: 4b - a = 15
Step-by-step explanation: if you replace the variables with their equivalent counterparts you get the equation 4(7) - 12 = __ when you do the math make sure to do the parentheses first then subtract, just like in elementary school remember pemdas parentheses, exponents, multiplication, division, addition, subtraction. I hope this helps.
