Here's a graph of linear function. write the equation that describes that function. express it in slope-intercept form.

Step-by-step explanation:

We are given graph of line and to find the equation of line.

First we mark two point on line and then find equation of line.

Slope intercept form:

y=mx+b

where, m is slope and b is y-intercept.

Please see the attachment for graph and point.

Two points:

(0,5)  and  (8,7)

using two point formula to find the equation,

Hence, The equation of line is

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: it is a.,b.,d.
