Question

The slope of the line below is too. Use the coordinates of the labeled points find a point slope equation of the line.

Answer 1

`\bold{y-10=2(x-3)}` {D?}

Explanation:

`y-y_1=m(x-x_1)` - point-slope form of Equation of the Line

`(3,10)\ \ \implies\ x_1=3\,,\ y_1=10\\\\b=4\ \ \implies\ x_2=0\,,\ y_2=4\\\\m=(y_2-y_1)/(x_2-x_1)=(4-10)/(0-3)=(-6)/(-3)=2\\\\equation:\\{}\qquad\qquad y-10=2(x-3)`
