50 pints ! what is the slope of the line shown in the graph? (4 points) a coordinate plane is shown with points graphed at 2 comma 2 and 0 comma 1. the points are joined by a line. −2 −1 −1 over 2 1 over 2

1 over 2

Step-by-step explanation:

Slope formula:

m = y₂ - y₁ / x₂ - x₁

Two points are given:

(2,2) and (0,1)

m = 1 - 2 / 0 - 2

m = -1 / -2

m = 1/2

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
