Question

Write the equation of the line with a slope of 2 that passes through the points -2 -7 and 5 7

a.y-7=2x+5
b.y=2x
c.y=2x+3
d.y=2x-3

Answer 1

Hello!
Really, we could finish this problem without knowing the slope or just having one of the given points.
However, since they gave us the slope, let's take the easier way.

y = 2x + b
To find b, we can plug in one of the points. (it doesn't matter which)
7 = 2(5) + b
7 = 10 + b
b = 7-10 = -3

So, the final equation is y = 2x - 3 or answer choice D.

Hope this helps!! let me know if you have ANY questions.
