Answer:
Take two points and connect them with a line.
Step-by-step explanation:
We can take the points (0,-4) and (1,-). Now we can connect the two points with a line and we get our graph.
Answer:
(See the third picture)
Step-by-step explanation:
Start by turning everything to slope-intercept form:
Next, plot down the y-intercept on the graph (which in this case is -4):
(The y-intercept is the point where a line crosses the y-axis, thus, the y-intercept must be (0, y))
(See the first picture)
Next up, plot down the next point with the slope, recall that the graph is rise over run, or more specifically, y over x.
The slope is 7/3, the rise is 7 and the run is 3, so to draw the next point, start at your y-intercept, and go 7 units up, and 3 to the right, the next point should look like this:
(See the second picture)
And finally, draw a straight line across both points:
(See the third picture)

Answer:
Step-by-step explanation:
We'll assume the correct expression to be factored is
One must try to find out if the expression is a perfect square. To test it, we'll take the square root of the first and the last term. If they are exact, we'll procceed with the next step
Since both are exact, we'll test if the middle term is twice the product of both square roots:
We confirm the middle term equals the above expression. All tests confirm the original expression is
The required factoring is
