Find the slope and y-intercept of the line represented by the table.

Answer:

slope: 9/3

y-intercept: 1

Step-by-step explanation:

slope: change in y / change in x

so if you look at your table ,you have to figure out how y and x are changing and see what is the pattern , so for x the pattern will be +3 and for y will be +9

which means 9/3  and if you look at your table there is a 0 that is the intercepts so if x=0, y = 1 because of the pattern we just solve.

y=9/3x+1

slope = 3

y-intercept = 1

explanation

slope, m = (y2-y1)/(x2-x1)

= (19-10)/(6-3)

= 9/3

= 3

equation of a line is y = mx + c

at point (3,10)

=> 10 = 3*3 + c

=> c = 10-9

=> c = 1

finding y-intercept when x = 0

y = mx + c

by putting the values we have

y = 3*0 + 1

y = 1

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2. 6x + 11 3(x + 7) 2(3x + 16) 3x

2(3x+16)

Step-by-step explanation:

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4

4(x + x + 7) − 2x + 8 − 4

When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38

When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44

Plug in x=1  and check with each expression

6x + 11 =6(1) +11= 16

3(x + 7) = 3(1+7)= 3(8)= 24

2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2

2(3x + 16) = 2(3(2)+16)= 44

3x + 16= 3+16= 19

Answer:

A is on a line with the slope of 2/3

Step-by-step explanation:

the rule is that you do y2-y1 over x2-x1 which you do 4-2 over 8-5 and your final answer you would get 2/3.

hope this helped!
