Hi there!
The general form of the equation of a line in slope-intercept form is
y = ax + b
With 'a' representing the slope of the line. We know that the slope of this line is 1/4, so we can plug in this value into the equation of the line.
y = 1/4 x + b
When the line passes through the point (0,0) we can also plug in the x- and y-coordinate into the equation, and we'll see that some easy algebra will help us find our solution.
0 = (1/4) * 0 + b
First switch sides
(1/4) * 0 + b = 0
Multiply
0 + b = 0
b = 0
Now we've found our value of 'b', which we can plug back into the equation in slope-intercept form to find our final solution.
y = 1/4 x
or
f(x) = 1/4 x
~ Hope this helps you!

Answer:
See photo below
Add arrows to the two ends of the parabola.
Step-by-step explanation:
To sketch this quadratic function, we to connect three dots: the two roots and a vertex.
The given roots are -1 and 1.
Draw <u>two dots at the x-intercepts</u>, which are (-1, 0) and (1, 0).
Vertex dot: V (x, y)
The vertex x-coordinate always in the middle of the two roots. The middle of -1 and 1 is 0. That's the same as the y-axis.
V (0, y)
Since the function increases when x < 0, the parabola will <u>open up</u>.
We read from left to right. The greater numbers are towards the top of the page.
<u>You can put the vertex anywhere on the y-axis that is below the x-axis.</u>
