Write an equation of the line that is parallel to y = 1/2x + 3 and passes through the point (10, -5).a) y = 2x - 15 b) y = -2x + 15 c) y = - 1/2x d) y = 1/2x - 10

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b"

For lines to be parallel, the slopes have to be the same.

The given line's slope is 1/2, so the parallel line's slope is also 1/2.

y = 1/2x + b

To find "b", you can plug in the point (10, -5) into the equation.

y = 1/2x + b

-5 = 1/2(10) + b

-5 = 5 + b    Subtract 5 on both sides to get "b" by itself

-10 = b

y = 1/2x - 10    Your answer is D (you could have just found the slope to get your answer, since all the slopes are different)

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

f(x) = y

f(-3) = -5
