Question

graph the equation by plotting three points 2y=5x+11

Answer 1

(1,8)
(3,13)
(-1,3)

Answer 2

3,13 is not one of the answers ibsmart

Answer 3

that's not the answer

Answer 4

oh wait, you're trying to find the three points not the graph

Answer 5

yes

Answer 6

what do you mean answer? If you substitute 13 for y and 3 for x into the equation, it works.

Answer 7

13 is not one of the points on the graphg

Answer 8

I need to find what the three points that make the equation true

Answer 9

use a table of values

x: -1 : 1 : 3 substitute them into the equation to find y
---------------
y: 3 : 8 : 13


plot the ordered pairs, (-1, 3) (1, 8) and (3, 13)

on the numberplane then draw a long line through all 3 points

Answer 10

2(13)=5(3)+11
26=15+11
26=26
True

Answer 11

the point 13 is not on the graph it goes up to 10

Answer 12

why not just substitute an x value to find a y value and the ordered pair will be on the line

x = 1

2y = 5*1 + 11

2y = 16

so y = 8 plot the ordered pair (1, 8)

repeat the process with values like -1 and 3

Answer 13

Then try (-3,-2)

Answer 14

well it is on the line, its just that the number plane is not large enough to include it


so choose x = -3, x = -1 and x = 1

substitute those values to find the ordered pairs

Answer 15

ok

Answer 16

in a question of this type.... you choose the values for x....

then substitute to find the corresponding y values

if you do it correctly you can draw a line through all 3 points

Answer 17

I got (-3,-4) (-1,6) (1,16)

Answer 18

how can you get an ordered pair of x = -1 and y = 6


\[2y = 5 \times (-1) + 11\]

then

\[2y = -5 + 11\]

so

\[2y = 6\]

what is y...?

Answer 19

3

Answer 20

can someone please help me

Answer 21

so the 1st point to plot on the number plane is (-1, 3)

now for x = 1

\[2y = 5 \times 1 + 11\]

I'll let you solve this

Answer 22

1,16

Answer 23

no same mistake as before

2y = 16 what is y..?

Answer 24

8

Answer 25

so plot (1, 8)

now substitute x = -3

\[2y = 5 \times (-3) + 11\]

whats the value of y

Answer 26

-2

Answer 27

thats correct... so on the number plane plot your 3 points

(-3, -2) (-1 , 3) (1, 8)

if you have calculated correctly you can draw a straight line that passes through all 3 points

Answer 28

thanks so much that that was correct

Answer 29

glad to help
