slope (M) = (y2-y1)/(x2-x1)
x1 =3, y1= -5, x2 = 5, y2=5
= (-5-5) / (3-5) = -10/-2 = 5

<span>. 2 verbal expression
of 2d
Verbal expressions in mathematics is the
translation of the given mathematical equation or numbers into words. For
example the verbal expression of operations are:
+ = addition
- = subtraction
/ - division
x = multiplication
In the given number of 2d, these are the two verbal expression:
2d => 2 times d; or 2 multiply by d
2d => the product of 2 and d
Verbal expression are the words translation of mathematical equations.

Answer: (x, y) = (3, 4)
This is the same as saying x = 3 and y = 4 pair up together
======================================================
Explanation:
Subtract the equations straight down.
- The x terms subtract to 5x (because -5x-(-10x) = -5x+10x = 5x)
- The y terms subtract to 0 (because 2y-2y = 0)
- The right hand side values subtract to 15 (because -7-(-22) = -7+22 = 15)
After all that is said and done, we have this new equation
5x = 15
Divide both sides by 5 to get x = 3
Then we use this x value to find y
-5x+2y = -7
-5(3)+2y = -7
-15+2y = -7
2y = -7+15
2y = 8
y = 8/2
y = 4
Or,
-10x+2y = -22
-10(3)+2y = -22
-30+2y = -22
2y = -22+30
2y = 8
y = 8/2
y = 4
Either way, we end up with y = 4.
Overall, the solution as an ordered pair is (x, y) = (3, 4)
If you were to graph the two equations, they intersect at the location (3,4).
