We basically have to cancel values on both sides until they are both on common ground.
7 + 3x = 5x + 13
-7 from both sides...
3x = 5x + 6
-5x from both sides...
-2x = 6
/-2 from both sides...
x = -3
Hope this helps!
You can find the slope of a linear function by taking two points and finding the change in y over change in x.
Hm, but the values you gave for the tables don't make sense for a linear function/relationship. But let's just pick two points as an example.
So two points you can pick are (-2, 13) and (1, -3).
The slope, change in y over change in x is in other words (y2 - y1 / x2 - x1), where (x1, y1) is one point and (x2, y2) is another.
(-3 - 13) / (1 - -2) = -16/3 = -(16/3)
Or you could have switched up the order of those coordinates but you still get the same answer.
(13 - -3) / (-2 - 1) = 16 / (-3) = -(16/3)
Sorry idk how to do that either
(4,-2)(5,0)
slope(m) = (0 - (-2) / (5 - 4) = 2/1 = 2
there is going to be 2 possible answers...
y - y1 = m(x - x1)
now we sub
using points (4,-2)..... y -(-2) = 2(x - 4) =
y + 2 = 2(x - 4) <==
using points (5,0)....y - 0 = 2(x - 5) <==
The answer is A
I know this because Alvin is the one who has the greatest amount of points.
