Question

Find the slope of the line that has a y intercept of 4 and passes through the point (-3, 1)

Answer 1

Line L1 : Passes thro' (3,3)

y-intercept = 4 ===> (0,4)

Slope = (4 - 3)/(0 - 3) = 1/-3

Slope of L1 = -1/3.

Explanation:

Answer 2

Answer: m = 1 (m is slope)

Explanation:

1. y-int is coordinate, so it is (0,4)

2. with (0,4), we can now use (-3,1):
4 - 1 = 3 and with the x, it is 0 + 3 = 3
So, it is 3/3 = 1, so the slope is 1
