Question

How do you write an equation of a line given Slope= 8, y-intercept= (0,-10)?

Answer 1

y = 8x - 10

Explanation:

The equation of a line in `color(blue)" sope-intercept form"` is

`color(red)(|bar(ul(color(white)(a/a)color(black)(y=mx+b)color(white)(a/a)|)))`
where m is the slope and b, the y-intercept.

Here the slope is 8 and the y-intercept is - 10

Substitute these values into the equation to obtain.

`rArry=8x-10`
graph{8x-10 [-22.5, 22.5, -11.25, 11.25]}
