Question

Find the equation of the line below. Arrange your answer in the form y = mx + b, where b is the constant.

Answer 1

where does the line cross the \(y\) axis?

Answer 2

-3 @satellite73

Answer 3

ok, then you know it looks like
\[y=mx-3\] your job is to find \(m\)
do you know how to do it?

Answer 4

No @satellite73

Answer 5

ok lets look at the points labelled \((0,-3)\) and \((4,-1)\)
going to the right from \(0\) to \(4\) is 4 steps , yes?

Answer 6

do you see what i am talking about?

Answer 7

okey yah

Answer 8

then from \(-3\) to \(-1\) is up \(2\) units
over 4, up 2, slope is \(\frac{2}{4}=\frac{1}{2}\)

Answer 9

final answer is therefore
\[y=\frac{1}{2}x-3\]
