OpenStudy (anonymous):

What is the approximate equation of this line of best fit in slope-intercept form? y = −13x + 13 over 10 y = negative 13 over 10x + 13 y = negative 10 over 13x + 13 y = −13x + 10 over 13

OpenStudy (anonymous):

@damian87 pretty please help lol

OpenStudy (anonymous):

on the y axis right

sammixboo (sammixboo):

The slope intercept formula is y = mx + b Remember, b is the y-intercept, and m is the slope. Do you know how to find the intercept?

sammixboo (sammixboo):

Not the y axis, but the y-intercept. The y-intercept is the point where the line crosses the y-axis

OpenStudy (anonymous):

yea thats what i meant

sammixboo (sammixboo):

Okie dokie, do you know what the y-intercept is?

OpenStudy (anonymous):

13

sammixboo (sammixboo):

Right! So we can exchange b for 13 y = mx + b y = mx + 13 Now we must find the slope, Since the line is going down, our slope will be negative.

OpenStudy (anonymous):

so were down to B and C

sammixboo (sammixboo):

Right

OpenStudy (anonymous):

i think C

OpenStudy (anonymous):

am i right

sammixboo (sammixboo):

Nope, but do you know why it isn't C?

OpenStudy (anonymous):

no can you explain please

sammixboo (sammixboo):

Well, let's stat from our first point, (0, 13). If we first go down 10, and go over to the right 13 spaces, do we land on another point?

OpenStudy (anonymous):

ohh, no.. so its B?

sammixboo (sammixboo):

Right :)

OpenStudy (anonymous):
