Answer: B. (5,3)</h3>
How to get this answer:
x+y = 8 solves to y = -x+8 after isolating y. You subtract x from both sides.
Plug this into the second equation and solve for x
3x + 2y = 21
3x + 2( y ) = 21
3x + 2( -x+8 ) = 21 ... replace y with -x+8
3x - 2x + 16 = 21
x + 16 = 21
x = 21-16
x = 5
Use this to find y
y = -x+8
y = -5+8
y = 3
We have x = 5 and y = 3 pair up to get the ordered pair solution (5,3)
Hello from MrBillDoesMath!
Answer:
m = 0
b = 22
Discussion:
I will ignore the duplication of the point (15,22) and "y=mx+b" mentioned in this question.
A line parallel to the x axis is of the form
y = <constant>.
Since the line passes through (15,22), the above constant must be 22. That is,
y = 22 = 0x +22 = mx + b
so m = 0 and b = 22
Thank you,

Why?
linear functions have only the slope, they dont include the y-intercept

Hopefully the math was self-explanatory. If it is not, please feel free to ask for a step-by-step, in depth explanation, and I will edit my answer to accommodate.
x - intercept is were the graph intercepts the x axis the maximum is the largest y value on the graph
increasing 1-3 and decreasing 3-6
4/3 slope
