Question

A line with a slope of -2 passes through the point (4, 7). Write an equation for this line in point-slope form.y – 7 = (x – )

Answer 1

Hi Lj,

The point-slope form in general is y - y₁ = m (x - x₁) where m is the slope and (x₁, y₁) is the point given to us. That means we have y - 7 = -2 (x - 4).

Please let me know if I can be more helpful, thanks!

Answer 2

Point-slope form is: (y-y₁)=m(x-x₁).

A point is (x,y) and the point in this example is (4,7). Slope is -2 so m = -2.

Therefore, the equation in point-slope is (y-7) = -2(x-4)
