How to find the angle between two lines given their slopes?

1 answer:

3 0

Tan(tan−1(yx)−θ) is the slope m. Then use "point slope formula" (if you want an equation of the line, that is...) Labeling the origin "O" and the point (x,y) "P", the segment ¯OP makes an angle of tan−1(yx) with the positive x-axis

Answer:

y=2x+6

Step-by-step explanation:

y=mx+b

your two point that are [-1, 4] with 1 as x and 4 as y

replace y with 4 then replace m with 2 then put your negative one in () it should look like this

4=2(-1)+b then do what in Parentheses

that will give you -2 then add 2 to 4 and that will give u 6

y=2x+6
