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
