Answer:
y = 11/2x + 29
Step-by-step explanation:
Find the slope of the 2 points using the formula m = y2-y1/x2-x1
So, (-4) - 7/(-6) - (-4)
Therefore, our slope is equal to -11/-2, 2 negatives make a positive, so finally our slope is equal to 11/2.
Pick a point, in this case I'll use (-4,7) use the formula y - y1 = m(x - x1)
Plug in, we get y - 7 = 11/2(x - -4)
Again, 2 negatives make a positive, so let's rewrite our equation.
y - 7 = 11/2(x + 4)
Distribute, and you get y - 7 = 11/2x + 22
Add 7 to both sides, final answer is y = 11/2x + 29.
Remember these formulas. To find the slope use m = y2-y1 over x2 - x1.
Then, after finding the slope of 2 points, use y - y1 = m (x - x1).
Remember, when finding the y = mx + b form of two points, only use one point to create the point-slope form.
Hope this helps!
This just the way I do it.
Take your y from your second ordered pair, then subtract it by the y from your first ordered pair.
-4-7
Then put it over a line, and underneath it take your x from your second ordered pair, and then subtract it by the x from your first ordered pair.
-4-7
-6-(-4)
Then solve. Well, -4-7 is -11.
-11 .
-6-(-4)
Then solve the bottom. The two negatives make a positive, so instead of -6--4, it can be seen as -6+4. -6+4 is -2.
-11
-2
-11/-2 is the same thing as 11/2
Divide (if your teacher likes it simplified fully)
The answer would either be 11/2, 5.5 or 5 1/2, depending on the way you like it, or the way your teacher wants it.
