Scientist created a scatter plot to represent the heights of four plants over time. Then, she found a line of best-fit to model the height in centimeters of each plant after x days. The equations of each trend line are given in the table. 1.) y = 3/2x + 3/2
2.) y = 2x + 1
3.) y = 1/2x + 3
4.) y = 3/2x + 1
According to the trend line equations, which plants are growing at the same rate per day?

A.) 1 and 2

B.) 1 and 4

C.) 2 and 3

D.) 2 and 4

B

Step-by-step explanation:

1 and 4 are growing at the same rate each day because they have the same slope, which is 3/2.

In the form y = mx+b, m is the slope, and in both 1 and 4, the slope is 3/2, meaning that they are growing at the same rate because slope = rate.

4.6875 pounds

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
