Question

The equation of line CD is y =-2x -2 write an equation,of a line parallel to line cd in slope-intercept form that contains (4,5)
Y=-2x +13
Y=-1/2x+7
Y=-1/2x+3
Y=-2x-3

Answer 1

a parallel line will have the same slope...so can u tell me the slope of the given equation ?

Answer 2

-2x-2

Answer 3

not quite. In y = mx + b, the slope is in the m position.
y = mx + b
y = -2x - 2
as u can see, the slope is -2
understand so far ?

Answer 4

Yes

Answer 5

now we use y = mx + b
slope(m) = -2
(4,5)...x = 4 and y = 5
now we sub...we are looking for b, the y intercept
y = mx + b
5 = -2(4) + b
can u finish and solve for b ?

Answer 6

5=-8+b
13=b
Answer is y=-2x +13

Answer 7

correct

Answer 8

Thank you so much
