ex. y= 2x+3
The slope is how the line slopes so this one would be 2 or on the graph, up 2 and right 1.
The y-intercept is where the line crosses the y-axiz or (0,3).
So plot (0,3) and go up 2 right 1 for about 3 points and if you need more you can reverse the direction and go down 2 left 1.

How do you solve linear equations by graphing them?
Assuming you want to plot two linear equations, you plot the graphs of both, and look where they intersect. One way to plot a linear equation is to convert it to the form y = ax + b; in this case, a is the slope, and b is the y-intercept - the coordinates where the line crosses the y-axis.
When you graph linear equations by plotting points the points you plot should all be what?
... plotted accurately.
Where the given equations are not linear?
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
How are linear equations and functions alike?
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
How are functions and linear equations similar?
Linear equations are a small minority of functions.
