Can someone please give me an equation in slope-intercept form for this graph?
Scilla [17]

Answer:

substitute y = mx +b = (2/3)x -2

Step-by-step explanation:

slope intercert form looks like this

y = mx + b

m is the slope

b is the y intercept

The line intercepts the y at -2

To find slope, pick 2 points to find the slope

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

i select point 1 (0,-2) and point 2 (3,0)

m = (0-(-2))/(3-0) = (2)/3

substitute y = mx +b = (2/3)x -2

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
saw5 [17]

Using exponential function concepts, it is found that it represents a decay of 0.9%.

<h3>What is an exponential function?</h3>

A decaying exponential function is <em>modeled </em>by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function is:

A(t) = 9300(0.991)^{6t}

Hence:

1 - r = 0.991

r = 0.009

Thus, it represents a decay of 0.9%.
