<span>x=3y-8
3x-4y=-9
We are told that:
</span>x=3y-8
So replace x in 3x-4y=-9 with x=3y-8 like so:
3(3y-8)-4y=-9
Start by distributing the 3:

Now you have:

Combine like terms, now you have:

add 24 to both sides

Now you have:

Divide both sides by 5 to get:
y=3
Now that you know y=3 plug it into:
x=3y-8
x=3(3)-8
x=1
Final answer: (1,3)
Answer: f(x)=mx+b
f(x)=x+7
if x=2 then
f(2)=2+7=9
A function is linear if it can be defined by
f(x)=mx+b
f(x) is the value of the function.
m is the slope of the line.
b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
x is the value of the x-coordinate.
