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.

Quadrilateral, Parallelogram, and a Rhombus
Theoretically she couldn’t spend that amount if money and thus her account balance will be negative. -61.72, to be precise.
Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.
75) Here, oly option D can fit i the equation, we can check:
3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.
76) Here, only option D is your answer,
4(2) - 4 = 8 - 4 = R.H.S
Do the same thing in every equation!
Hope this helps!
