Question

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains point (3, -2). (4 points)
Question 4 options:
1) y = -2x + 4
2) y = x -
3) y = x -
4) y = 2x - 8
*Help please

Answer 1

hmm well.. what's the slope of y = 2x + 4 anyway?

Answer 2

1) y = -2x + 4
2) y = -1/2 x - 1/2
3) y = 1/2 x - 7/2
4) y = 2x - 8

Answer 3

ok... so... what did you get for the slope of y = 2x + 4 again?

Answer 4

is it D ?

Answer 5

Answer 6

Point slope form is y-y1= m(x-x1). Parallel lines have the same slopes. Plug in 2 for m and plug in the coordinates.
y-(-2) = 2(x-3).
y+2 = 2x-6.
y = 2x-8.

Answer 7

so it's D? @ridoleor

Answer 8

Yes it is.

Answer 9

thank you @ridoleor
