Answer:
14. (0,1)
Step-by-step explanation:
To find the solution set, substitute and evaluate each point into the given equation. If it makes it true then it is part of the solution set.
14. y = 4x + 1
(2,-1)
-1 = 4*2 + 1
-1 = 9 FALSE
(1,5)
5 = 4*-1 + 1
5 = -3 FALSE
(9,2)
2 = 4*9+1
2 = 37 FALSE
(0,1)
1 = 4*0+1
1=1 TRUE
In order to get an equation is slope intercept form, we need to find the slope.
The formula is:
y2 - y1
———-
x2 - x1
In this case:
10 - 2
———
7 - 3
=
8/4
2
Now that we know the slope, we can plug it into y = mx + b with x and y being x1 and y1.
y = 2x + b
10 = 2(7) + b
10 = 14 + b
-4 = b
Now, we can construct our equation.
y = 2x - 4

Hello,
What we want to do is multiply 1/6 by each value within the parentheses individually.
So, it would be:
(1/6) * (18x) = 3x
(1/6) * (-24) = -4
Together, this would be 3x-4.
Hope this helps!
