Answer:
1,5,6
Step-by-step explanation:
You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)

Answer:
y = 1/3x -1
Step-by-step explanation:
We have 2 points (9,2) and (42,13)
We can find the slope
m = (y2-y1)/(x2-x1)
= (13-2)/(42-9)
=11/33
=1/3
The slope is 1/3
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-2 = 1/3(x-9)
Distribute
y-2 = 1/3x -3
Add 2 to each side
y-2+2 = 1/3 x-3+2
y = 1/3x -1
