Question

Which equation has a slope of-7 and passes through the point(0,5)?

Answer 1

`y=-7x+5`

Explanation:

In the general equation `y =mx +c`
`m` is the gradient and `c` is the y intercept
`y=-7x +c` when `x=0, y=5` because the point (0,5) is on the line. Substitute these values to confirm the equation. graph{-7x+5 [-20, 20, -10, 10]}
