Y=3x+7; (2, 10)

B. y= 3x+4 
C. Y=-3x+4 
D. Y=(1/3)x+4

The slope of the parallel line will have the same slope as the given line.

anonymous · Answer

Use the formula y = mx+b....and the point (2,10) to help finish the equation

anonymous · Answer

hint they have the same slope so plug them in to $$y-y_1 = m (x-x_1)$$ then put it into $$y = mx+b $$ form. the M is the slope, the b is the y -intercept

anonymous · Answer

Paralell means the slope are the same (meaning that the slope = 3), so choice D is eliminated.

A. Y = 3x + 11
plug in (2, 10)
10 = 3(2) + 11
10 = 17 false.

B. Y = 3x + 4
plug in (2, 10)
10 = 3(2) + 4
10 = 10

So the answer is B.
