This is confusing, I need some help on it

y=x+5

Step-by-step explanation:

Looking at the answer choices, at first glance you see x=0 and y=5, this mean the y-intercept is 5. And in the equation y=mx+b, positive 5 will go into b.

The only answer with +5 as y-intercept is y=x+5

Now what if there are multiple +5 for y-intercept?

If there is multiple +5, you will also need to find the slope, you can find the slope by using

y2-y1/x2-x1

(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.
