And we also noticed we got the y equals mx

plus b thing working for us here Let's Think about

this too right The equation of a line Remember we

just need those two pieces of information The line slope

and it's Why intercept it's Kind of like a user

name and password Once a hacker gets a hold of

them while it's all over So the why intercept on

the line is the location where the line crosses the

y axis Well the graph shows us that the y

intercepted this line is negative five seen right there That

is where the line crosses it So the why Intercept

is negative five All right so we can cross out

these other two so a and see it ain't it's

Got to be other b or d here starting at

the y intercept and moving to the point to comma

zero right there The line moves Five units up and

two to the right So what's slope Yeah Five half

remember its rise over run to it rises five and

it runs to all right Well put the slope and

the y intercept be together in the form y equals

mx plus b And the equation of line is Why

equals five halves X minus five The answer is the 00:01:25.349 --> [endTime] for er done
