Answer:
Explanation:
Use any two of the three points. Which is right: the givens for the table in the picture. Or the 4 you have listed for y?
I'm going to use -1,5 and -4,11 and as a confirmation -7, 17. If this is not correct, leave a note at the bottom of my answer.
y2 = 5
y1 = 11
x2 = - 1
x1 = - 2
m = (y2 - y1) / ( x2 - x1)
m = (5 - 11) / (-1 - - 2)
m = -6 / 1
m = - 6
Use -1,5 to find b
y = 5
x = - 1
5 = -6(-1) + b
5 = 6 + b
b = - 1
Equation
y = -6x - 1
Confirmation
x = -7
y = 17
17 = -7*- 6 - 1
Apparently the question is incorrect. The right side is 41, which is nowhere near 17.
If you can correct it in the next hour put a comment somewhere telling me what the third point is and what to do with the 1. Otherwise I'll simply have to report it.
