When trying to find the point-slope equation of a line you need to pick a point and plug it into the plain equation with your slope.
-3 = 1/3(-1) +b
Multiply your slope with your x
-3 = -1/3 +b
Move the -1/3 to the other side by doing the opposite operation, in this case being addition.
-3 +1/3 = b
-2 2/3 = b
y = 1/3x - 2 2/3
Out of the ordered pair the 2 would be the x so you would need to plug in 2 for x in the equation so it would look like this
y=2(2)+2
finally solve for y
4+2
6=y
6 is your answer
Answer:14.9129
Step-by-step explanation:
I usually do this 26 - 8 = 18 so v equals 18. to check if it is correct add 8 + 18. Hope i helped
