what is the slope of the line ? It's passing through the points of -6 and 9. Write answer as a simplified fraction

OpenStudy (anonymous):

We'll need more information here, but the slope between two points is equal to the difference in their y values over the difference in their x values: \[m=\frac{ \Delta y }{ \Delta x }\]

OpenStudy (anonymous):

9/-6 ?

OpenStudy (anonymous):

??

OpenStudy (mertsj):

Please post the problem EXACTLY as written.

OpenStudy (anonymous):

We need more information.

OpenStudy (anonymous):

all it says is whats the slope of the line and theres a picture of a graph .

OpenStudy (mertsj):

Then find two points on the line and post them.

OpenStudy (anonymous):

It wont let me copy the graph. But theres a line passing through the points of -6 and 9 which i already said.

OpenStudy (mertsj):

A point has two coordinates...an x and a y coordinate. That's why no one has been able to help you. You don't give us two ordered pairs.

OpenStudy (mertsj):

An ordered pair looks like this: (-3,5)

OpenStudy (mertsj):

If we know two ordered pairs that are on the line, we can find the slope.

OpenStudy (anonymous):

(-6,0) and (9,0)

OpenStudy (mertsj):

slope = \[m=\frac{y _{2}-y _{1}}{x _{2}-x _{1}}\]

OpenStudy (mertsj):

Also, I think at least one of your ordered pairs is incorrect because a line cannot cross the x axis two times.

OpenStudy (anonymous):

hold on . im going to draw the graph

OpenStudy (ybarrap):

Using @Mertsj 's formula and your two points, slope is zero.
