Answer 2

I need to make an equation

Answer 3

notice how as x increases by 2 each time, y increases by 1 each time

so

rise = 1
run = 2

Answer 4

slope = rise/run = ???

Answer 5

-1/2

Answer 6

close, it should be 1/2

Answer 7

now use the first row in the table to see that

x = 1, y = -12



y = mx + b

y = (1/2)x + b ... plug in the given slope

-12 = (1/2)(1) + b ... plug in x = 1 and y = -12

-12 = 1/2 + b

b = ???

Answer 8

algebra 1 need simpler terms please!

Answer 9

which steps aren't making sense?

Answer 10

what I did was start with y = mx + b

this is the general slope intercept equation

Answer 11

then I plugged in

m = 1/2
x = 1
y = -12

Answer 12

slope = m = -11 --12 / 3 -1 = 1/2
b = y -mx
b = -11 - (1/2)*3
b = -11 -1.5
b = -12.5

b = y -mx
y = b + mx
y = -12.5 + .5x
