Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 1 ) and (x₂, y₂ ) = (5, 4 )
m =
=
=
= 
Answer:
The percent increase of her collection is 60%
Step-by-step explanation:
Divide 24 by 15 to get your answer which is 1.6. Since the decimal is .6 and it is one digit behind the decimal, you can safely assume it is 60%
Answer:
( 10,20 )
Step-by-step explanation:
Y=2x
Y= 3x -10
What is the solution to the system of equations?
2x=3x-10 *combine like terms*
-1x= -10 x=10 *divide*
Y=2(10) y=20 *plug in for y into other equation*
CHECK:
plug both x and y into both equations to get a true statement.
Y=2x 20=2(10) 20=20
Y= 3x -10 20= 3(10) -10 20=20
Answer:
(x+4,y+5)
Step-by-step explanation:
If you look at the differences in the x and y rows t=you can see that x is added 4 each time and y is add 5 each time.

The slope of line is negative. Therefore, correct answer is D.
