Question

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

Answer 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

Answer 2

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
