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).

Answer 1

Using y = mx + b, what is the slope of this lie given?

Answer 2

line* .-.

Answer 3

Well since you won't respond, the slope is -2, and since parallel lines have the same slope the new line will also have a slope of 2. Point slope form looks like this:

\[(y _1 - y _2) = m(x _1 - x_2)\]

Where m is the slope. So now with the slope and points given we can determine that the equation of the line will be:

\[(5 - y _2) =- 2(4 - x _2)\]

Answer 4

Remove the 2 from y and x.
