If the slope is the same, they are parallel.

[Also, if the slopes of the two lines multiply to -1, they are perpendicular.]

The slope-intercept form is y = mx + b where m and b are constants.

If two different equations in this form both have the same value for m, they are parallel.

Example

y = 3x + 3

y = 3x - 10

As the top answer suggests, m is the slope.

Q: How can you tell if two equations in slope- intercept form would graph as parallel?

The slope-intercept form of the equation is y = mx + b, where m represents the slope and b represents the y-intercept. It is used to graph linear equations easily.

To graph an equation that is not in slope-intercept form, you can use the process of finding points on the graph and plotting them. Choose a few x-values, plug them into the equation to find the corresponding y-values, and plot those points on the graph. Then, connect the points with a smooth line to complete the graph.

It makes it easier to work out values for x and y for graph plotting purposes.

If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither

It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept

If you were to graph both equations side by side, you would see that they are parallel lines. Both equations have the same slope it is just that the line would be moved down in the graph because of the intercept change.

When the equation of a line is parallel to another line the slope remains the same but the y intercept changes

If you mean: y = 0.5x-10 then an equation parallel to it will have the same slope of 0.5 but a y intercept different to -10

They have the same slope. If you write the lines in the slope-intercept form, you will get, for each line: y = ax + b where a is the slope, and b is the y-intercept (where the line crosses the y-axis). For two or more parallel lines, the coefficient "a" will be the same.
