Answer:
The equation of the line with a y-intercept of 4 and a point (8,8) is 
Step-by-step explanation:
A linear equation can be expressed in the form
y = m * x + b
where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.
Graphically this equation represents a line.
In this case, you know:
- The point (x,y)=(8,8)
- Y-intercept= 4
Replacing:
8=m*8 +4
Solving:
8-4=m*8
4=m*8
4÷8= m

Then, <u><em>the equation of the line with a y-intercept of 4 and a point (8,8) is </em></u>
<u><em></em></u>
Any relation is x and y is said to be a Direct variation if one is a constant multiplier of the other .In other words we can say : when one variable changes the other changes in proportion to the first.
The Direct variation equation are of the type y=k.x
Here k is known as constant of proportionality .It has a fixed value.
The given equation is y=
If we compare this equation with y=k.x
Then k=
The two numbers would be 4 and 8 because they add to 12 and when I do 8-4, it equals 4.
It’s C.
6(1) = 6
6(2) = 12
6(3) = 18
6(4) = 24
6(5) = 30
