+ 
= 225 + 64 = 289
289 = 289
Hence its a right angled triangle

To find how many minutes of talk time is available per dolla, you have to divide 160 (number of minutes) by 40 (cost)
160/40 = 4

Answer:
y = -
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
= - 
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = -
x + 3 ← equation of line
