After 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have a line of best fit:
y = 2.5 + 1.25x
Plug x = 7 weeks
y = 2.5 + 1.25(7)
y = 11.25 units
Thus, after 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.

Answer:
what did they do?
Step-by-step explanation:
One solution:
x= 0
Y = 3x+ 4 = 4
Another solution:
x = -3
Y = 3x + 4 = -5
Another solution:
x = -1
Y = 3x + 4 = 1
Another solution:
x = 1
Y = 3x + 4 = 7
Another solution:
x = 5
Y = 3x + 4 = 19
Another solution:
x = -10
Y = 3x + 4 = -26
Another solution:
x = 10
Y = 3x + 4 = 34
Answer: Neither
Step-by-step explanation:
y = -5/4 x + 3/4
y = 5/4 x + 3/4
Because -5/4 is not a negative reciprocal of 5/4 and because they are not the same, they are neither in parallel or perpendicular
