I have a multi-part question that I am struggling with. I have an equation of y=-(2/3)x+30. A man shines a beam from a 3rd story window onto the pavement. The path of the beam is represented by the above equation. Y represents the height above the ground, x represents the distance from the face of the building. I have been asked to find the X and Y intercepts which I have, (0,30) and (45,0). Now it is asking to identify the point on the graph that most accurately represent the location of the 3rd story window as an ordered pair and the location where the laser beam hits the ground as an

amistre64 · Answer

you seem to have already defined them as ordered pairs

anonymous · Answer

so the answer to that second part would be the same as the X and Y intercepts?

amistre64 · Answer

the y-intercept is 30
the x-intercept is 45

in point notation .. (0,30)  and (45,0)

amistre64 · Answer

one is asking for a numerical value that identifies with the "axis" that is being intercepted

the other is asking for a "point" value in the xy plane ....
