What is the slope of a line that passes through the point (−1, 1) and is parallel to a line that passes through (4, 6) and (−1, −4)?

Question

lgbasallote · Answer

use (4.6) and (-1,-4) as slope...then use (-1,1) for x1 and y1 in $$\huge y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)$$
does that help?

anonymous · Answer

no really what would the equation  be if you substitute the number in?

lgbasallote · Answer

kinda like $$\huge y - 1 = \frac{-4 - 6}{-1 - 4} [x - (-1)]$$

anonymous · Answer

so y-1=-2[x+1]???

lgbasallote · Answer

close...but not -2

anonymous · Answer

oh positive 2?

lgbasallote · Answer

yup..now simplify the equation

anonymous · Answer

thats what i need your help.. how do i do that from here?

lgbasallote · Answer

wait...i just realized it was just asking for slope o.O well the slope is just 2...
