Okay First,
Start with the given equation <span>Subtract from both sides
Rearrange the equation
Divide both sides by
Break up the fraction
Reduce
Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

Answer:
you must send 25 msgs to have the same cost
Step-by-step explanation:
x = n of messages
15+ (0.25x ) = 20 + (0.05x)
0.2x = 5
x = 25
X = 2, y = -1 Answer = -1
x = 0, y = 2.5 Answer = -11.25
x = -1, y = -3 Answer = 14
x = 0.5, y = -0.1 (one tenths) Answer = 0.44
x = 0.75 (three quarters), y = 0.4 (two fifths) Answer = 1.665
x = 1.41 (sqareroot of 2), y = 1.41 (sqareroot of 2) Answer = 9.17
I hope this helps!
