Question

write an equation in point-slope form and slope-intercept form for a line that passes through point(4,-1) and has a slope of -3

Answer 1

Point Slope:
`(y-(-1)=3(x-4)`

Explanation:

`y-y1=m(x-x1) Point Slope Form\\plug in:\\y-(-1)=3(x-4)\\`

`Slope Intercept is y=mx+b\\Find Y Int (b):\\b=-13\\Plug in;\\y=3x-13`
