How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
What is the definition of graph intercept?
The intercept of a graph is the point where is crosses one of the coordinate axes. The x intercept is where it crosses the x axis, the y intercept where it crosses the y axis. If the graph is given as y equals a function of x, it is usually easier to find the y intercept, because that is where x is 0. You just plug in 0 for x and evaluate. To find the x intercept, you plug in 0 for y and then you have to solve an equation for x. This is fairly easy if it is a linear equation (the graph is a straight line), somewhat harder for a quadratic (a parabola). But anyway you only asked for a definition, and I have given it.
Which types of lines match these equations 2x - 3y equals 2 x plus 2y equals 8?
2x - 3y = 2The graph of this equation is a straight line, which crosses the y-axis where [ y = -2/3 ]and has a slope of 2/3 .x + 2y = 8The graph of this one is also a straight line, which crosses the y-axis where [ y = 4 ]and has a slope of -1/2 .
What part of graph would you shade on an equation if the answer is 0 equals 0?
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
How do you graph the equation 8x plus 2y equals -1?
Same way you graph y = -4x - 0.5

How do you find the zeros in an equation by looking on a graph?
They are all the points where the graph crosses (or touches) the x-axis.
How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Graph the equation -5y equals -40?

What is the answer for y equals 3x plus 1?
y = 3x + 1 is a linear equation - it is the equation for a graph of a straight line that crosses the y axis at 1 and the x axis at -1/3, and has a gradient (slope) of 3.
What is the y-intercept of a linear equation?
The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
The graph of the line with the equation Begin equation y23x-7 crosses the y-axis at which of the following values of y?
At -7.
What does the graph of the equation y equals 3 look like?
You get a straight line (parallel to the x-axis) that passes through only the y-axis, and it crosses the y-axis at (0,3)
What does the graph of the equation 2x-3y equals 6 look like?
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
How can you tell by looking at a graph whee the solutions are in a quadratic equation?
Let's say you have the quadratic equation x2 - 7x + 12 = 0. Plot the graph of y = x2 - 7x + 12. Where y = 0 (when the graph crosses the x-axis) is a solution to the equation. In this case, it crosses at the points (3,0) & (4,0) so the solutions are x = 3 and x = 4. Now if the graph never touches the x-axis, that means the solutions to the equation are complex numbers.
