What arethe coordinates of the following point

(a) Lying on both axes-  

Point lying on both axes will lie on origin, so its coordinate is (0,0)

(b) Lying on x-axis and with x-coordinates 4

Since the point lies on x-axis so its y-coordinate is 0, so its coordinate is (4,0)

(c) Lying on y-axis and y-coordinates -3

Since the point lies on y-axis so its x-coordinate is 0, so its coordinate is (0,-3)

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
