please help will medal and fan Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6). y = 1/3x + 7 y = -3x + 3 y = 1/3x + 3 y = -3x + 7

OpenStudy (anonymous):

I think its a just wanna be sure

OpenStudy (anonymous):

A*

OpenStudy (anonymous):

a line that is parallel to the first line should have the same slope. So you should be able to eliminate two choices if you know the slope-intercept formula. Next, you will need to plug in the x and y values of the point given and solve for the y-intercept

OpenStudy (anonymous):

\[y=mx+b\] Slope intercept formula

OpenStudy (anonymous):

the slope intercept form is y=mx+b right

OpenStudy (anonymous):

the answer is not A. Yes that is the slope intercept form, where m is the slope, b is the y-intercept and x and y are coordinates for the x and y axes respectively.

OpenStudy (anonymous):

ok but it doesn't say the slope

@Blonde_Gangsta please help

OpenStudy (anonymous):

give me a minute

OpenStudy (anonymous):

thank you np

OpenStudy (anonymous):

Im going for y = -3x + 3 but im not great at this, so dont go all mad on me if its wrong lol

OpenStudy (anonymous):

its ok I wont you tried thank you

OpenStudy (anonymous):

welcome

OpenStudy (anonymous):

r u available to help with another its like this but theres fractions

OpenStudy (anonymous):

That answer is correct, but the way you find what the y-intercept is you need to plug in the point given into: y=mx+b, you know that m = -3. plug in the values of x and y and solve for b

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

thank you the both of you
