Determine another point on the line given two points on the line. (-2, 9), (2, -1)
Gnom [1K]

Answer:

(4,-6)  

Step-by-step explanation:

1) First, let's find the slope of the line between the two points. Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}, substitute the x and y values of (-2,9) and (2,-1) into it, then solve:

m = \frac{(-1)-(9)}{(2)-(-2)}\\m = \frac{-1-9}{2+2} \\m =\frac{-10}{4} \\m = -\frac{5}{2}

So, the slope of the line is -\frac{5}{2}.

2) Now, using that slope, let's find another point on the line. You can do this by drawing the two points on a graph (picture below). Now, remember that the slope is \frac{rise}{run}. So, starting from any of the two points (I chose (2,-1), as seen below) count 5 units down, then 2 units to the right. This gives an answer, (4,-6).

Mark recorded the growth of a plant over 8 weeks. The equation y=0.2x+2 represents the height y, in inches, after x weeks.
klio [65]

Answer:

Step-by-step explanation:

The equation representing the growth of the plant after x weeks is expressed as

y = 0.2x+2

Where

x represents the number of weeks.

y represents the height of the plant after x weeks in inches.

A.

The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes

y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.

B is incorrect.

C.

The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes

y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.

D is incorrect
