Answer:

How you can tell

Step-by-step explanation:

A function assigns exactly one output to each input: x/input y/output

How they work: X <u>can not repeat</u> but Y <u>can</u>.

Lets see your problem, there are no inputs repeating and the outputs are fine.

That is a function!

write the equation of the line that passes through the points (-1, 2) and (6,3) in slope-intercept form
ElenaW [278]

Answer:

<h2>y=(1/7)*x+(15/7)</h2>

Step-by-step explanation:

first, lets find the slope:

m=(y2-y1)/(x2-x1)

m=(3-2)/(6-(-1))

m=1/7

y=(1/7)*x+b

to find b lets pug in a point we know into the equation:

3=(1/7)*6+b

21/7=6/7+b

b=(21/7)-(6/7)

b=15/7

now we know the equation in slope intercept form representing this function is:

y=(1/7)*x+(15/7)
