Answer 2

the equation is
y = slope(x - x_1) + y_1
or
y - y_1 = slope(x - x_1)

Answer 3

What do you think is the answer?

Answer 4

B or C @adamaero

Answer 5

y = mx + b

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

-4 = (1/2)*(2) + b ... plug in the given point (x,y) = (2,-4)

solve for b

Answer 6

i did all the work.

Answer 7

-4=1+b and b is what -4 ?

Answer 8

@jim_thompson5910

Answer 9

-4=1+b does not lead to b = -4

Answer 10

hmmmm well then how do u solve for b if b is unknown

Answer 11

try thinking of 1+b as b+1

Answer 12

-4=1+b

1+b = -4

b+1 = -4

b = ????

Answer 13

ummm b=-5?

Answer 14

yep so the equation is \[\Large y = \frac{1}{2}x-5\] since m = 1/2 is given and you found that b = -5
