Answer:
f(x) = -3x + 4
Step-by-step explanation:
3y = -9x + 12
y = -3x + 4
The equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A).
<h3>What linear equation best fits the scatter plot?</h3>
The equation of the line is represented by a polynomial of the form y = m · x + b, where m is the slope of the line and b is the intercept of the line. The slope is equal to the change in the <em>dependent</em> variable (Δy) and in the <em>independent</em> variable (Δx) and the intercept is the <em>vertical</em> distance of the line with the origin when x = 0.
In accordance with the picture, we notice that the scatter plot indice that Δy < 0 and Δx > 0 and therefore, m < 0. Besides, the intercept of the equation of the line must be greater than zero. Thus, the equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A)

Answer: the answer is C
Well if you follow PEMDAS you would have to do the parentheses first but you can’t subtract 18 from a variable (Z) so then you move on to the 2 and you have to do the opposite so you don’t multiply both sides by 2 you have to divide both sides by 2. And that’s how u get C
