Question

3. Write an equation in point-slope form that describes the line with a slope of 2 that contains the point (4,-3)?

Answer 1

y + 3 = 2 (x - 4)

Explanation:

y - y₁ = m (x - x₁)

substitute (4, -3) in for (x₁, y₁)

y - (-3) = m (x - 4)

substitute the slope (2) in for m (m=slope) and simplify (y - (-3)) to (y +3) because subtracting a negative is the same as adding a positive

y + 3 = 2 (x - 4)

and that's your final answer! hope this helped :)
