Answer:

Step-by-step explanation:

7-5

-21-0

-2/21. the y intercept would be 5, considering the x is 0 on the first pair of coordinates. so y=-2/21x+5, or A

Answer:

y = -2/21(x)+5

Step-by-step explanation:

We know that the formula to find the slope of an a line y = mx + b where m is the slope and b is the y-intercept.

The formula of slope is m = (y2-y1)/(x2-x1)

Using the two points given, we can find the slope:

m = (7-5)/(-21-0)

m = -2/21

b = 5 because (0,5) is the y-intercept

y = -2/21(x)+5

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?
IgorC [24]

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

  • Length of a tree = 3/4 meters
  • Total time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 years

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.

Find the slope between the points (-3, -2) and (5, 4) (type in integer or reduced fraction you found only)
DiKsa [7]

Answer:

The slope is: \frac{3}{4}

Step-by-step explanation:

The equation for slope is:

m=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }

Point 1: -3=x_{1}, -2=y_{1}

Point 2: 5=x_{2}, 4=y_{2}

4-(-2)=6

5- (-3)=8

6/8=3/4
