I need to know if I got this right or not.
Write the equation of the line that passes through (–2, 6) and (2, 14) in slopeintercept form.
y = 2x – 2 << my answer but I'm not sure
y = 2x + 10
y = 0.5x + 7
y = 0.5x – 4

Best ResponseYou've already chosen the best response.0Start with the slopeintercept form of the equation of a line. Then plug in the given points. This is how you do it. \(y  y_1 = \dfrac{y_2  y_1}{x_2  x_1}(x  x_1) \) \(y  6 = \dfrac{14  6}{2  (2)}(x  (2)) \) \(y  6 = \dfrac{8}{4}(x + 2) \) \(y  6 = 2(x + 2) \) \(y  6 = 2x + 4) \) \(y = 2x + 10 \) The answer is choice B. To check, you can confirm that both points work in the equation of choice B. Choice A is not correct. In fact, neither point works in the equation of choice A.
