Question

Hi can anyone please help me with this problem, I’d really appreciate it

Answer 1

We can start this equation off by noticing the fact that this is a linear equation, which we can write in the form of:
`mx+b`. We can plug in our x values and y values given. I am going to start on the second line:

We plug in the given point:
`(0,-3.2)`.

`-3.2=m(0)+b\\-3.2=b`

We can also plug in the point
`(4,0)` to get:

`0 = m(4) -3.2`

We get
`m = 0.8`

Therefore, our equation for the SECOND line is:

`y = 0.8m - 3.2`

Hope that this helps you do the first line.
