Step-by-step explanation:
Slope = y2-y1 / X2-x1
= 8-4/2-(-3)
=4/5
3x-14=4x-9
-4x -4x
-x-14=-9
-14 -14
-x=-15
-x/-1=-15/-1
x=15
Sorry if this is a bit confusing, but I hope I helped
Answer:
D
Step-by-step explanation:
12-y=2x-5
+5 +5 ( add 5 to both sides)
17-y=2x
-17 -17 (Subtract 17 to get y by itself)
-y=2x-17
divide by -1 because y cant be negative
y=-2x+17
m=-2 and y-intercept= 17
I hope thats right :)
Answer:
Step-by-step explanation:
A. Rate of change (or slope) is $50
The initial tutoring fee starts out at $1200 in 2005
How do you know? Each year the cost goes up $50
2005 = $1200
2006 = $1250
2007 = $1300
2008 = $1350
B. y=50x+b
