What I would do for this problem is figure out the equation of the line first, then substitute for x, 1.

britanyashton · Answer

Pick any two points on the line. Tell me its rise/run (or in other words, its slope.)

britanyashton · Answer

Also, what is the y intercept? It is between -1 and -2

britanyashton · Answer

From looking at it, what can you guess it is (the y-int)?

anonymous · Answer

so -1.5

britanyashton · Answer

yes. thats the x intercept. whats the slope of the line using rise/run?

britanyashton · Answer

y intercept*

anonymous · Answer

i dont know

britanyashton · Answer

rise over run. 
m=y2-y1/x2-x1
sorrry i was helping someone. 
pick two points and plug them into this equation to find the slope 
any two points.
