3) Find the slope and the y-intercept of the line. Write fractional answers in lowest terms. 6y+2x+6=17+2x
The slope is ?.
The y-intercepts is [0,?]
1.
f(- 
= (- 8)^3 = - 512.
2.
F(t) = $625 - $25t.
F(t) = $25(25 - t).
3.
6y + 2x + 6 = 17 + 2x
6y = 11
y = 11 / 6.
Slope = 0.
y intercept = (0,11 / 6).
