Answer:
(y2-y1)/(x2-x1)
Step-by-step explanation:
Average rate of change is just using the slope formula: (y2-y1)/(x2-x1)

now, the midline for the parent function of sin(x) is simply the x-axis, namely y = 0.
this shifted/transformed version of it, has a vertical shift of 4 units down, so the midline moved from y = 0, to y = -4.
Answer:
Line R
Step-by-step explanation:
we know that
A<u><em> line of best fit</em></u> is a straight line that best represents the data on a scatter plot.
This line may pass through some of the points, none of the points, or all of the points.
From the given graph the line R passes through 2 points. The number of points above the line is equal to the number of points below the line.
therefore
Line R is the line of best fit
Answer: (1,-6)
Step-by-step explanation:
Let's solve your equation step-by-step.<span><span><span>
2/3</span><span>(<span><span>3x</span>+1</span>)</span></span>=5</span>
Step 1: Simplify both sides of the equation.<span><span><span>
