Hello !

Answer:


\Large \boxed{\sf y=-(1)/(3)x+3 }

Explanation:

The slope-intercept form of a line equation is
\sf y=mx+b where m is the slope and b is the y-intercept.

The slope of the line ( with
\sf A(x_A,y_A) and
\sf B(x_B,y_B) ) is given by
\sf m=(y_B-y_A)/(x_B-x_A) .

Given :

  • A(0,3)
  • B(3,2)

Let's calculate the slope :


\sf m=(2-3)/(3-0) \\\boxed{\sf m=-(1)/(3) }

The y-intercept is the value of y when x = 0.

According to the graph,
\boxed{\sf b=3}.

Let's replace m and b with their values in the formula :


\boxed{\sf y=-(1)/(3)x+3 }

Have a nice day ;)

The equation that represents the graphed function is:

y = -1/3x + 3

In this graphed function, 3 represents the y-intercept (or the point where the line crosses the y-axis). -1/3 is a representative of the slope (or the linear pattern in which the line moves). The equation is written in slope-intercept form, which is shown by:

y = mx + b

where m represents the slope, and b represents the y-intercept.

Given the points (0,3) and (3,2), we can find the slope first:

2 - 3 = -1
3 - 0 = 3
m = -1/3

Now, we simply look for the point where the line crosses the y-axis (in this case, 3).

Hence, our equation is: y = -1/3x + 3
