Question

A. Find the slope of the line that passes through the points (2,-5) and (-2,3).

b. What are the slope and y-intercept of the equation 2x - 5y = -10?
c. Find the x value so that the line through the points (x,-9) and (0,1) has a slope of -4.
d. Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b.

Answer 1

A. (2, - 5)and (-2, 3)

Explanation:

M=a2-a1 /b2-b1

-2-2/3--5

-4/8

4/4

=2

D. (-1,5) and - 7

y=mx+b

-1=5(2)+-7

-1=10-7

-1=3

3/3

=-1/3
