Which relation is a function?

{(5, 0), (–8, –5), (–8, 5), (–5, –8)}
{(5, 0,) (–8, –5)}
{(5, 0), (0, 5), (–5, –5)}
{(5, 0), (0, –8), (5, –5)}

Answers

Answer 1

Answer:

B. C.

Step-by-step explanation:

when you have a function, you can only have one input for every output, like in A

{(5, 0), (-8, -5), (-8, 5), (-5, -8)}

we have -8 twice in the sets of numbers on the X, so this set is NOT a function

another way to tell is to plot out the points on the graph, then draw a vertical line and run across the sets, if more then one point cross the line at a time, then those points are not a function, this is called a vertical line test

hope this helps, it looks like a multiple choice maybe, bc B. and C. are both functions from what i can see, i hope this was worth the points u spent on this question

take care :)

y= -2/3x-4

Step-by-step explanation:

Answer:

y=2/3x-4

Step-by-step explanation:

y=mx+b is slope intercept form so the y intercept is -4, which is b in the equation. so y=mx-4 and then m is the slope which is 2/3 so

Complete the equation of the line through (2,1) and (5,-8)
Use exact numbers.

y=

Answers

y=-3x+7

Because
y=mx+b

m= slope (3/-1 which simplifies to -3)

b= y-intercept (y-intercept is where the line hits the y axis, which that line hits the line at the y intercept of 7

so when u put it into an equation, you have your answer of:
y=-3x+7

Answer:

D

Step-by-step explanation:

since all you need to do is set up the equation 4/5/2/3 which is basically dividing the fractions so it would be set up as this 4/5*3/2 which is 12/10 and simplifed would be 6/5 also 6/5*2/3 is 4/5 so it would be the correct answer.
