M= (7-1)/(2-0)=3
y=3x + c
plug in Q 
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2

y – 1 = 3x

since Q is (0,1) that would make 1 the y-intercept.

using a formula to find the slope we end up with 3.

1 is a negative because when moved to the other side it must be positive.

Eli wants to plant 45 sunflower plants, 81 corn plants and 63 tomato plants in his garden. If he put the same number of plants i
Lynna [10]

Answer:

9

Step-by-step explanation:

For this problem, you would use the GCF

Find the GCF of 45, 81, 63

GCF(45, 81, 63) = 9

45 = 9 * 5

81 = 9 *9

63= 9 * 7

Since 5, 9, 7 have no common factors, the GCF has to be 9.

This means that the greatest number of plants he can put in each row is 9.

The number of rows he uses for each plant will (obviously) vary.
