Question

Which table corresponds to the graph above?

Answer 1

marc you got this or need help?

Answer 2

Step 1 : Find two points on a line in the graph
let say,I choose two coordinates which are \((x_1,y_1)=(-3,4)\) and \((x_2,y_2)=(0,-5)\)

Step 2 : Find the gradient of the line using those two points
\(slope,m=\frac{y_2-y_1}{x_2-x_1}\)
sub. those values into the formula of gradient
\(m=\frac{-5-4}{0-(-3)}\)
\(m=\frac{-9}{3}\)
\(m=-3\)

Step 3: use the slope intercept form to find c
\(y=mx+\color{red}{c}\)
where
\(m=slope\)
\(c=y-intercept\)
Use any of those two points and slope to find c
let say,we choose\((x,y)=(0,-5)\)
\(-5=-3(0)+c\)
\(c=-5\)
Rearrange the eqn
\(y=-3x-5\)

Step 4: Sub. those values of x into that eqn to find y
If the y values u find are the same as the values of y in the table,therefore,that's the answer

Answer 3

seems like you got this covered let me know if you need help mkay

Answer 4

sorry,I was busy typing,haha...
sure @SkyVoltage43 ;)

Answer 5

.

Answer 6

so i do that for each one?

Answer 7

As u can see that,the y-intercept of the eqn is \(-5\)
so,option A and B will be crossed out
so,we r left with option C and D

Answer 8

When u try to observe,option C and D,
almost all of the coordinates are the same except the last coordinate

Answer 9

Okay

Answer 10

i cant see pnt rn

Answer 11

Option C- \((x,y)=(1,-8)\)
Option D- \((x,y)=(1,-7)\)
In order,to find the correct coordinate,use that eqn
\(y=-3x-5\) and sub the value of \(x=1\) into that eqn to find the value of y
\(y=-3(1)-5\)
\(y=-8\)

Answer 12

i cant see pnt rn


It's okay.
Based on the print screen,Im trying to tell u that Option C and D almost hv same values except for the last value at the right which I already wrote (above this comment) ^^

Answer 13

Okay because im dull and i saw -8 i think its c

Answer 14

yes,the answer is C

Answer 15

Thank you so much i owe your my left sock and shirt with my left lung

Answer 16

lol,no prob (=
