Slope 1, passes through (2, 5)

see below

Step-by-step explanation:

The point slope form is

y-y1 = m(x-x1)

y -5 = 1 (x-2)

y-5 = x-2

In slope intercept form

Add 5 to each side

y-5+5 = x-2+5

y =x+3

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
