How do I work out this 1 problem...?

Question

Give an ordered pair that is the solution to the equation y = 5x + 2.

I don't know how to work it step by step out???

Answer 1

First, pick a number for x.  Any number.

I'll pick x = 1

Plug that into the equation and solve for y.

y = 5(1) + 2

y = 5 + 2

y = 7

So the ordered pair is (1, 7).

You can do this with just about any number for x.

Answer 2

giving an ordered pair that is a solution to an equation is just like saying give us a point that would be on this graph. so all you have to do is pick a random number to be x. plug it in the equation and get y.

let x = 1

y= 5x+2

y = 5(1) +2

y = 5+2

y=7

so when x=1, y=7. as an ordered pair, that is (1,7).

let's do another using x=5

y=5x+2

y=5(5)+2

y=25+2

y=27

answer: (5,27)

Answer 3

choose a value for x in the equation and calculate y..

for example, let x=0, so y=5(0)+2=2, so the point (0,2) is a solution to the equation...note that since this is a linear equation, there an infinite number of solution to this equation

Answer 4

No steps involved. Just mathematical common sense. It will be

(x, 5x+2) for any real x.

Answer 5

first let x=0

then y=2 so the first ordered pair is(0,2)

then put x=1

then y=7

and son , u can have infinite number of ordered pairs like this
