Step-by-step explanation:
The given blue line has a slope of m = -1/2.
The line parallel to the given line passing through point (x0,y0)=(2,3) is given by the point-slope form:
(y-y0)=m(x-x0)
substitute values
(y-3) = (-1/2)(x-2)
Expand and transpose
y = (-1/2)x + 1 + 3
y = (-1/2)x + 4 ....................(1)
We choose the second equation b. x+2y=8 and convert to slope-intercept form:
2y=-x+8
y = (-1/2)x + 4, which is exactly equation (1)
So
b. x+2y=8 is the correct answer.
2.5x10^3 I think. Exponents are subtracted. The number you're multipliying by has to be more than one.
A) $6.17 each X 4 poster boards = $24.68 total
B) $200.20 total / 4 lights = $50.05
C) $200.20 on lights + $24.68 on poster boards = $224.88 spent in total
$300 available - $224.88 spent = $75.12 left over to spend
