Answer:

Step-by-step explanation:

A, C and D are already in the fraction form so they are rational

E is 9.4 which is also 47/5. That's also rational.

B can not be written in the fraction form, because it's not a recurring decimal. Hence not rational

Find the equation of the linear function represented by the table below in slope-intercept form.

ollegr [7]

Answer:

y = -3x-4

Step-by-step explanation:

First we find the slope

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

= (-16 - -7)/(4-1)

= (-16+7) /3

= -9/3

= -3

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -3x+b

Using a point

-10 = -3(2)+b

-10 = -6+b

-10+6 = b

-4 = b

y = -3x-4
