Answer:
m = 3, c = 0
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 )
y = 3x , or y = 3x + 0 ← is in slope- intercept form
with m = 3 and c = 0
Answer:
2.5 hours
Step-by-step explanation:
The product of speed and time is distance. If the distance is the same, then time is inversely proportional to speed. At 60/50 = 6/5 times the speed, the return trip will take 5/6 times the time:
(5/6)(3 hours) = 2.5 hours . . . time for return trip

Answer:
(- 1, 0) and (9, 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0 in the equation and solve for x, that is
x² + y² - 8x - 8y - 9 = 0
x² - 8x - 9 = 0 ← in standard form
(x - 9)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 =0 ⇒ x = 9
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (9, 0 )
