Question

Ronald correctly wrote the equationof a line through point g as y=mx-4. What is the value of min Ronald's equation

Answer 1

`m = -2`

Explanation:

Given

`y = mx - 4`

See attachment for graph

Required

Find m

From the graph, we have:

`(x,y) = (-4,4)` at point G

Substitute these values for x and y, respectively in:
`y = mx - 4`

`4 = m * -4 - 4`

`4 = -4m - 4`

Collect like terms

`-4m=4+4`

`-4m=8`

Solve for m

`m = -2`
