Question

Kwenziee
y= 350 + 0.015(x)
Michael:
y=0.052x


hwo do v graph it..can u tll me da praph numbers....x is time(month)...y is money($)

Answer 1

Find the x-intercept for both equations. Start at the least x-intercept.
. . . x y = 0.052x . y = 350 + 0.015x
-23,333 . . . -1,213 . . . . . . . 0
-20,000 . . . -1,040 . . . . . . 50
-10,000. . . . . -520 . . . . . 200
. . . . . 0. . . . . . . . 0 . . . . . 350
. 5,000 . . . . . 260 . . . . . 425
. . 9,459 . . . . . 491 . . . . . 491
. 10,000 . . . . . 520 . . . . . 500
Doing a strictly graphical solution, you would not have the exact intersect point. You would have to read it off the graph.

Answer 2

Eqn of K: draw straight line between (0,350) and (1, 350.015)

Eqn of M: draw straight line between (0,0) and (1, 0.052)



Done by substituting x as any values to get y (I did x=0 and x=1 for both)
