The same way one would graph y=-2x+4. First use 0 as x and insert it into the formula to find the y-value to find the x-intercept. Then repeat this process with the y-intercept. After finding this, use four or five simple numbers (usually -2, -1, 0, 1, and 2) for the x-values and find the corresponding y-values. Graph these coordinate pairs and you're set!

How do you rewrite the equation y - 42x equals 24 as a function of x?
y-42x = 24 >> Add 42x to both sides << y=24+42x >> Subtract 24 from both sides << y-24=42x >> Divine both sides by 42 << x=(y-24)/42
Which of these graphs correctly illustrates the solutions to these equations (You may click on each graph to enlarge it.)y = 42x + y = 2?
a
When x equals 8 and y equals - 4 find the value of 2x - y?
x = 8y = -42x - y = 2(8) - (-4) = 16 + 4 = 20
What describes the translation of the graph of y equals x2 to obtain the graph of y equals -x2 - 3?
No translation will invert a quadratic graph.
What happens to the graph of y equals x when the equation changes to y equals x - 9?
The graph shifts downward (negative y) by 9 units.
What is the transformation of the graph of y equals x2 to obtain the graph of y equals -x2 plus 3?
First, reflect the graph of y = x² in the x-axis (line y = 0) to obtain the graph of y = -x²; then second, shift it 3 units up to obtain the graph of y = -x² + 3.
Graph the line y equals 5?
y= -5
What describes how to translate the graph of y equals x to obtain the graph of y equals x plus 1 - 2?
3
How can you translate the graph of y equals x to obtain the graph of y equals x-4 plus 2?
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
What describes how to translate the graph y equals x to obtain the graph of y equals x plus 1 plus 1?
y=x+1 there for answer is 2
State the y-intercept for the graph y equals -4x?
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
Graph y equals 3x - 7 what is the y intercept?
-7
