Remember that point slope form is [tex]y-y_1=m(x-x_1)[/tex] where [tex]m[/tex] is the slope of the line and [tex](x_1, y_1)[/tex] are the coordinates of a point it passes through. Now in the problem the lines are parallel, which means they have the same slope: [tex]\dfrac{3}{4}[/tex]. So we can eliminate answer choices C and D. Now plug the coordinates [tex](-1,7)[/tex] into the equation to get answer choice B, [tex]y-7=\dfrac{3}{4}(x+1)[/tex].
