Question

What is the equation for the line?

Answer 1

y=4x

Explanation:

The line goes through the points (0, 0) and (2, 8).

You can plug these in to the slope formula, and the slope is 4

Since the line intersects the y-axis at 0, the y-intersect is 0.

Using these two pieces of information, you now know that the equation is

y=4x+0, or y=4x.

Hope this helps!

Answer 2

Y = mx + c

Explanation:

Where

m = gradient or slope

c = intercept (value of y when x=0)

Y = how far up

x = how far along
