Given m = 7 and the point (3, -1), which of the following is the point-slope form of the equation
2 answers:
Answer:
y = 7x - 22
Step-by-step explanation:
We know that point-slope form is y = mx + b (b is y-intercept, m is slope, and the y and x is of any point on the line)
We can plug in m as 7, y as -1, and x as 3 to get:
-1 = 21 + b
You can subtract 21 on both side to get b = -22.
Then, we plug in m = 7 and b = -22 to y = mx+b to get y = 7x + (-22) which simplifies to:
y = 7x - 22
Hope this helps! Answer is highlighted. If you have any questions you can ask.

Answer:
y=-1/3x +29/3
Step-by-step explanation
We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:
8= -5/3x +b.
B= 29/3
That's your answer.
6 and 10 are part of the 2 table so you would have 2(3x-5) thats the farthest we can factor it down :)
