Answer:
y =
x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y-intercept )
here m =
and b = 4, hence
y =
x + 4 ← equation of line
X>8
Sarah has more than eight goldfish in her tank
The formula for the volume of a cone is V= πr² (h/3).
V= 3.14 (12²) (8/3)
V= 3.14 (144) (2.6...)
V= 1205.76
V≈ 1206
So the answer is A.

In order to find the solution by graphing we need to make two equation with x and y terms
we use Left hand side 4x^2 for first equation and right side x^2 -7 for second equation.
So the equation becomes
first equation 
Second equation 
are the system of equations that can be graphed to find solution
