There are two ways to equate a straight line. We first have y=mx+b. Then, we have (y-y₁)=m(x-x₁). Both work fine and have similar variables, but the numbers are mixed around a bit. Your equation clearly shows the second form of equation. As our equation has x-x₁ on the right, we can notice that x+1 must mimic that, so x+1=(x-x₁). As x-(-1)=x+1, we can only assume that x is -1. Looking at the points given to us, y must be -2, so we have y-(-2)=y+2, so 2 fills in the leftmost open box. To find the slope, or m, we must take
from points (x₁, y₁) and (x₂, y₂). It doesn't matter which point is (x₁, y₁) , but it matters that the y₁ corresponds to the x₁. Thus, we have our slope as

7÷2=3.5 each of them get 3.5 cookies
3x and -2x are like terms because they both have the variable X
Answer:
Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer.
m=<u><em>y2-y1/x2-x1</em></u>
m=9-5/3-1
m=4/2
Simplify the answer.
m=4/2
m=2/1
Final answer is 2.
The slope is positive meaning it is ascending (going up).

Answer:
-6 = x / 3 -Multiply both sides by 3
-6 * 3 = x / 3 * 3
-18 = x
Now, you can check your answer:
-6 = -18 / 3
-6 = -6
Hope this helps!
