Question

Find the slope and y-intercept

Answer 1

Answer:

m=1/2

b=-1

Step-by-step explanation:

to find the slope, we need to see what values x and y increase by. in this table, we can see that as x increases by 2, y increases by 1. since slope is written as rise(x)/run(y), we can write the slope as 1/2.

for the y-intercept, we can use how the x and y values increase as well. we need to find the value of y when x is 0. we know that as x increases by 2, y increases by 1, so we need to do the opposite of both to find the y-intercept. this would be x decreasing by 2 and y decreasing by 1. we can make a table to find the y intercept.

x - 0, 2, 4, 6, 8, 10

y - -1, 0, 1, 2, 3, 4

we can see here that when x=0, y=-1, so that is the y intercept or b value.

Answer 2

Answer:

1/2 and -1

Step-by-step explanation:

Rise  = 2-1 = 1

corresponding Run = 6 -4 =2

rise/run = 1/2 = slope

So we know that when x=0 we will find the y intercept/

put them in ordered pair you will find

(6,2)

(4,1)

the next one should be (2,0)

and (0,-1)

So the y intercept is -1
