How will changing the 3 into an 8 in the equation y equals 2x-3 affect the graph?

First, you need to understand that y = 2x - 3 is the slope-intercept form of a line.
Remember from middle/high school algebra that the slope-intercept form of a line is:
y = mx + b
where:
m is the slope of the line
b is the y-intercept of the line
since -8 < -3, the y-intercept moves "down". Since the slope is unchanged, the rest of the line must also move "down".
I will leave the amount that the line moves "down" as an exercise for the reader ;)

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
Are there any online calculators that can graph an x equals equation instead of y equals equation?
Just swap the letter around in the formula that you are given!
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 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
How does changing the sign of the leading coefficient in an equation of the form y equals ax2 affect its graph?
It gets reflected in the x-axis.
Graph the equation -5y equals -40?

How does changing m affect the graph of an equation in the form ymx plus b?
It rotates the graph about the point (0, b). The greater the value of m, the more steeply it rises to the right.
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
What is the slope of the equation y equals -x?
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
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.
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.
What is an equation that can be written in the from Ax plus By equals C whose graph is a straight line?
A linear equation ?
What is the slope of a line when you are given the equation 3y equals -3x - 5?
The slope of the graph of that equation is -1.
Graph the equation and identify the y-intercept y equals 5x-7?
