To graph a linear equation, you must determine what a and b are for the equation y=ax+b. For this example, a=-1 and b=4. A is the slope and b is the y-intercept. The slope is the height of the line over the length of it. In this equation, the line goes down one unit for each unit right. The y-intercept refers to where the line crosses the y axis. For this example, it crosses the y axis at y=4. The line will cross the y axis at y=4 and then goes down and to the right and up and to the left. It will cross the x axis at x=4.

What is the effect on the graph of the equation y equals x2 plus 2 when it is changed to y equals x2 - 4?
the graph is moved down 6 units
X2 plus y2 equals 4?
The graph of that equation is a circle, centered at the origin, with radius = 2 .
How many solutions does x plus y equals 4 and 2x plus 2y equals 8 have?
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
How do you graph y-x plus 4 equals 0?
First convert it to Y= y-x+4=0 y=x-4 The graph has a slope of 1 and the y-intercept is (0,-4)
How many solutions are in x2 plus x plus 4 equals 0?
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis
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 is the effect on the graph of the equation y equals x2 plus 2 when it is changed to y equals x2 - 4?
the graph is moved down 6 units
Which equation has the steepest graph y equals 7x plus 3 y equals -2x plus 6 y equals -10x - 4 y equals 8x - 1?
y=-10x-4
Which direction would the graph of y equals x-4 plus 3 open?
Upwards.
What are two ordered pairs on the graph of y equals 2x plus 4?
(0,4) and (-2, 0)
X2 plus y2 equals 4?
The graph of that equation is a circle, centered at the origin, with radius = 2 .
How do you graph the equation yx plus 4?
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
How many solutions does x plus y equals 4 and 2x plus 2y equals 8 have?
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
How do you graph y-x plus 4 equals 0?
First convert it to Y= y-x+4=0 y=x-4 The graph has a slope of 1 and the y-intercept is (0,-4)
Graph -5x plus y equals -4?
-9
How many solutions are in x2 plus x plus 4 equals 0?
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis
Where does the graph y equals 2 to the power of x plus 3 plus 4 cut the y axis Please show working out?
y = 2x+3 + 4 cuts the y axis when x = 0 so y = 23 + 4 = 8 + 4 = 12. Therefore, the point is (0, 12).
