Question

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 slope-intercept form.
y = 2x – 2 << my answer but I'm not sure
y = 2x + 10
y = 0.5x + 7
y = 0.5x – 4

Answer 1

yes your answer is correct :)

Answer 2

thank you

Answer 3

np :)

Answer 4

Start with the slope-intercept 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.

Answer 5

Oops yes B is correct

Answer 6

oh yes B is correct sorry .
