SOMEONE PLEASE HELP ME

y = -(5/2)x - 1

Step-by-step explanation:

slope intercept form is y = mx + b

m is the slope

b is the y intercept

The y intercept is shown to be (0,-1), so b = -1

The equation is now y = mx -1

slope= rise/run

The rise is (4-(-1))=5

The run is (-2-0)=-2

5/-2 is the slope (m)

The equation is y = -(5/2)x - 1

y = -5/2 x-1

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (-1 -4)/(0--2)

   = (-5)/+2

   = -5/2

We know the y intercept is -1 since that is where it crosses the y axis

We will use the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = -5/2 x-1

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.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
