. Write the equation of a line that passes through the point (-1, 2) with a slope of - 5 2 in slope-intercept. B. Graph the equation of the line.

Nnesha (nnesha):

the thing you attach is empty

OpenStudy (stefrheart):

First there is nothing on the attachment Second you should put it into point slope formula

OpenStudy (rissyroo118):

ugh. idk how to attach the graph. sorry

OpenStudy (stefrheart):

Its okay

OpenStudy (stefrheart):

is the slope 5/2 or is it just 5?

OpenStudy (rissyroo118):

it is -5/2

OpenStudy (stefrheart):

Alright the best way to do this is to start with Point Slope form do you know that?

OpenStudy (rissyroo118):

no. honestly not sure of any thing with slopes

OpenStudy (stefrheart):

Its okay :)

OpenStudy (stefrheart):

the formula is y-y1=m(x-x1)

OpenStudy (stefrheart):

Do you know what your y1, m, and x1 are?

OpenStudy (rissyroo118):

i wanna say the slope?

OpenStudy (stefrheart):

M is the slope and x1 and y1 are the x and ys of the point (-1,2)

OpenStudy (rissyroo118):

so x1 and y1 repsent -5/2 ?

OpenStudy (stefrheart):

Now what would the formula look like?

OpenStudy (stefrheart):

No the -5/2 would represent the slope

OpenStudy (stefrheart):

the x1 would be the -1 and the y1 would be 2

OpenStudy (rissyroo118):

okaayy lol i thinking i'm starting to understand. So, i may be wrong but what you're saying is x1 and y1 represent 2 ?

OpenStudy (stefrheart):

here let me explain a little more in depth okay?

OpenStudy (rissyroo118):

okay. thank you, it's all very confusing.

Nnesha (nnesha):

the slope equation is y = mx + b where m is slope that you already have and b represent y -intercept and you have order pair which represent x and y

Nnesha (nnesha):

|dw:1412567902124:dw| plug this in to the equation and solve for b
