Question

How do you write an equation in slope-intercept form of the line that passes through (2,7); Slope: 1?

Answer 1

`y=x+5`

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=1`

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

`"to find b substitute "(2,7)" into the partial equation"`

`7=2+brArrb=7-2=5`

`rArry=x+5larrcolor(red)"in slope-intercept form"`
