Answer 3

do you know how to create a line using a slope and a point?

Answer 4

no

Answer 5

you are given the slope of 2
y=mx+b
so your line is y=2x+b because slope is the "m" value

Answer 6

(0,-1) happens to be your y intercept and that is your b value
y=2x-1
that is your equation
now all you have to do is figure out which of these points are on this line

Answer 7

sub each point in one at a time
for example
is (2,3) on the line
x=2 y=5
y=2x-1
5=2(2)-1
5=4-1
5=3 see how both sides are not equal, then it is false and thus (2,3) is not on the line

Answer 8

test the three given points for your solution in the same fashion
recall (x,y) First number is your x value and 2nd number is your y value

Answer 9

2,1?

Answer 10

no 1/1

Answer 11

seems like you are guessing

Answer 12

no ik what it is becaus e you said 0,-1 is my intercept so 1 up 1 would be ...

Answer 13

but your slope is not 1 so going up 1 is incorrect
your slope is 2 therefore you should be going up 2, right 1

Answer 14

it is best for you just to sub the values into the equation

Answer 15

(0,-1) you could start at this point and then go up 2 right 1 to determine other points
but then to find points below (0,-1) then you go in the opposite direction which is down 2 left 1

Answer 16

have you found the point yet?

Answer 17

yeah 2,1

Answer 18

(2,1) x=2 y=1
y=2x-1
1=2(2)-1
1=4-1
1=3 no because 1 does not equal 3

Answer 19

(1,1) x=1 y=1
y=2x-1
1=2(1)-1
1=2-1
1=1
this is the point you want
