9x-3y=3
3x+8y=-17

9x-3y=3
9x-3=3y
3y=9x-3
y=x-1
plug it into the other equation

3x-8y=-17
3x - 8(x-1) = -17
-5x + 8 = -17
-5x = -25
x = 5
plug it in again

y = x - 1
y = 5-1
y = 4

Select the linear equation represented in the graph.
AnnZ [28]
To find the linear equation, use the slope formula y = mx+b, where b is the value of the y-intercept and m is rise/run.

The line rises 1 unit and runs (left to right) -5 units. (you could also say the line runs -1 units and runs 5 units, they will both give the same answer). Rise/run, 1/-5 = -1/5.

The y-intercept is the y value where the line touches the y-axis. In this case, it is +1.

Plug the information into the equation. m = -1/5 and y = 1. y = -1/5x + 1

nekit [7.7K]
When you have lines in graphs for ex

Y=2x+7
2x is the rate of change

7 is the instant amt if the x=0 (or the y-intercept)

Which function has the greatest rate of exponential growth?
Veronika [31]

Answer:

C

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value
