# Is it possible to find the slope of a line if the equation has two ys?

Find slope of the line whose equation is 8y = 7 - 2y

Solve for y and you'll have a horizontal line.

Combine the y terms.
8y+2y=7
10y=7
y=7/10
The general equation for a straight line is
y = mx + b
m is the slope and b is the y intercept.
so what is m in the equation (if there is no x term)?
How would this equation look on a graph? That may help you decide the slope.

A slope shows the relationship between X and Y axes. You need both X and Y values.

I hope this helps. Thanks for asking.

## Yes, it is possible to find the slope of a line even if the equation has two ys.

To find the slope of the line with the equation 8y = 7 - 2y, we first need to solve for y.

Combine the y terms on the left side of the equation:
8y + 2y = 7
10y = 7

Divide both sides of the equation by 10 to isolate y:
y = 7/10

Now that we have solved for y, we can analyze the equation. The general equation for a straight line is y = mx + b, where m is the slope and b is the y-intercept. In this case, there is no x term, so the line is vertical and parallel to the y-axis.

Since there is no x term, the slope (m) is undefined. Vertical lines have an undefined slope because they do not have a rate of change in the x direction.

On a graph, this equation would represent a vertical line intersecting the y-axis at y = 7/10. The line would extend infinitely in both the positive and negative directions along the y-axis.

So, in this case, the slope is undefined and the equation represents a vertical line on a graph.
