Answer:
Step-by-step explanation:
Equation of a line is given as
Where,
m = slope of the line =
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.
Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m
b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>

Answer: See the graph attached.
Step-by-step explanation:
The standard form of a quadratic function is:
Where (h,k) is the vertex of the parabola.
If is negative, then the parabola opens down.
Then, for the function:
You can identify:
Then the vertex of the parabola is at (2,4)
Note that , therefore the parabola opens down.
Find the intersection with the x-axis. Substitute and solve for x:
Knowing that the vertex is at (2,4), the parabola opens down and it intersects the x-axis at x=0 and x=4, you can graph the function, as you observe in the figure attached.
