Y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b 
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
y = 4x

Answer:
w = 13
Step-by-step explanation:
Using the method of cross- multiplying
•  =
 =  ⇒ ad = bc, thus
 ⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13

<span>Set the two equations equal to each other and solve for x
 10x +50 = 8x +60
          -50 -50
-----------------
10x = 8x + 10
 10x = 8x + 10
           -8x -8x
---------------
2x = 10
2x = 10
divide by 2 on both sides
x=5
five additional services are needed for the two companies prices to be equal
