y = 2x +15

Explanation:

Since we have a point and slope, use the #color(blue)"point-slope form"# to establish the equation.

#color(red)(|bar(ul(color(white)(a/a)color(black)(y-y_1=m(x-x_1))color(white)(a/a)|)))#
where m represents the slope and # (x_1,y_1)" a point"#

here m = 2 and # (x_1,y_1)=(-6,3)#

Substitute these values into the equation.

#rArry-3=2(x-(-6))#

#rArry-3=2(x+6)rArry-3=2x+12rArry=2x+15#
