Answer:
Step-by-step explanation:
(x1,y1)=(2,5)
(x2,y2)=(6,0)
using formula
slope=y2-y1/x2-x1
=0-5/6-2
=-5/4
therefore slope=-5/4

I'm not sure how to find the answer to #3 and #5.
Our equation: 33x + 10 = 5 - 2x
Step 1:
To solve for x, we need to remember to isolate the variable (that is our way to solve for x). To do that, we add 2x on the right side of the equation to cancel -2x out. Then, we add 2x on the left of the equation. The equation becomes:

Step 2:
We subtract 10 from both sides (to cancel out the 10 on the left). Equation:

Step 3: Divide 35 on both sides to get our x value.
