Answer:
Hi how are you doing today Jasmine
The graph of a quadratic equation is a U-shaped curved called parabola. It is because the parabola makes very easy to find the axis of symmetry to plot selected points and finding the roots and vertex.
Good luck :)
We first need to find the gradient of the line

From the graph, we see the graph intercepts y-axis at -1
Hence, the equation of the line is
Answer:
y-intercept is 3
Step-by-step explanation:
We are given table
x: -8 -4 4 8
y: -3 0 6 9
We can select any two points


Firstly, we will find slope

now, we can plug values


now, we can use point slope form of line

we can plug values

now, we can solve for y

For finding y-intercept , we can plug x=0



So,
y-intercept is 3
Its f(x)=5x+5 (this is filling spaceskalekkejdkskwnedododkw)
