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 point (4, 5).

y = -2x + 13
y = x + 7
y = x + 3
y = − 2x − 3

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 point (4, 5). 
 	
	y = -2x + 13
	y =  x + 7
	y =  x + 3
	y = − 2x − 3

Firstly can you identify the slope of line CD?
[remember: y = mx + b where m = slope]
So for y = -2x - 2 , what would m/slope be ?

anonymous · Answer

-2x?

butterflydreamer · Answer

you're close but the "x" part won't be included for your slope :) It's just -2.
Like in your general formula : y = mx + b . ONLY the "m" is your slope.
So for y = -2x -2 , m = -2 :)

anonymous · Answer

u must resolve it with point x = 4, y =5
y=x+7
5 = 4+7
5=11
its not correct

butterflydreamer · Answer

Okay so now since we know that the slope of CD " -2 " 
We want to write an equation of a line that is parallel to CD and contains point (4,5)

Recall that the slope-intercept form is this :
|dw:1428563100532:dw|
