Which equation describes a line parallel<br> to y= 4x+ 5 through point (-2, 1)?
Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

\large\boxed{y - y_1 = m(x - x_1)}

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)

Simplify:

y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}

How would I solve 7r=-7/2? I know the answer is -1/2 I just don't understand how to get -1/2 as my answer.
Art [367]
7r=-7/2

divide both sides by 7 to get r by itself

(7r)/(7) = (-7/2)/(7)

if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)

(7r)*(1/7)=(-7/2)*(1/7)

r=-1/2
