Question

PLEASE HELP IT’LL BE WORTH IT

One line passes through (0, 1) and (4, 7). A second line passes through (-1, -1) and (1, -5). What is the slope of the first line? What is the slope of the second line?
a1-
a2-

Do the two lines intersect? If so where?
b1- The slopes are the same;the lines are parallel. They canning intersect
b2- The slope are the same; the lines are parallel. They intersect at (0, -2)
b3- The slopes are the opposite reciprocals; the lines are perpendicular. They cannot intersect.
b4- The slopes are the opposite reciprocals; the lines are perpendicular. They intersect at (-2, 0)

Answer 1

a1 3/2

a2 -2

b none of these are technically correct but the closest would be b4

Explanation:

y2 - y1 / x2 - x1

7 - 1 / 4 - 0

6/4 ~ 3/2

y = 3/2x + 1

y2 - y1 / x2 - x1

-5 + 1 / 1 + 1

-4/2 ~ -2

y = -2x - 3
