I got this by putting the numbers in their place
I'm pretty sure this is the answer but I'm not exactly sure....
3) y =
x + 3
Slope-intercept form is y = mx + b when m is the slope and b is the y-intercept
b = 2 (line hits y-axis at 2)
m =
so
and the line is negative, so 
Write our equation by putting the parts together, and we get:
y =
x + 3
4) y =
x - 1.67
Point slope form is y - y1 = m (x - x1) when y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate of the point
y - y1 = m (x - x1)
Finding the slope (same as above) results in

Answer:
x=.4
Step-by-step explanation:
Part A:5=2x^2-x^2+13
5=x^2+13
0=x^2+13-5
0=x^2+8
Part B:5=2x^3-x^3+13
5=x^3+13
0=x^3+13-5
0=x^3+8
