Question

What's the equation of a line with Slope=2,passing through (3,5)?

Answer 1

`y=2x-1`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`•color(white)(x)y=mx+b`

`"where m is the slope and b the y-intercept"`

`"here "m=2`

`rArry=2x+blarrcolor(blue)"is the partial equation"`

`"to find b substitute "(3,5)" into the partial equation"`

`5=6+brArrb=5-6=-1`

`rArry=2x-1larrcolor(red)"in slope-intercept form"`
