Question

Which equation in standard form has a graph that passes through the point (-4,2) and has a slope of 9/2?

Answer 1

`2y-9x-40=0`

Explanation:

Using the point gradient form

`(y-y_1)=m(x-x_1)`
Where m=gradient and `(x_1,y_1)` is a point on the slope

`(y-2)=9/2(x+4)`

`2y-4=9x+36`
`2y-9x-40=0`
