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.
