Question

anonymous · Answer

@AriPotta  can you help me plz??.. this is for Algebra 1

aripotta · Answer

use the slope formula

anonymous · Answer

Oh yea so it would be $$\frac{ 4 }{ 3 }$$

anonymous · Answer

For the equation –4y = 8x, what is the constant of variation?  (1 point)
–4
–2
1
2

anonymous · Answer

i think it might be -2

aripotta · Answer

yep

anonymous · Answer

ok so What is an equation for the line with slope $$\frac{ 2 }{ 3 }$$ and y-intercept 9

aripotta · Answer

well, you know slope-intercept form, right? just plug those into the equation

anonymous · Answer

i dont kno tht

aripotta · Answer

slope-intercept form is y = mx + b. m is the slope and b is the y-intercept

aripotta · Answer

so your answer would be y = 2/3x + 9

anonymous · Answer

Yea. I kinda guessed tht was the answer but i wasnt sure...

anonymous · Answer

What is an equation in slope-intercept form for the line that passes through the points (1, –3) and (3, 1)?

aripotta · Answer

find the slope, put it into point-slope form, then change it to slope-intercept

anonymous · Answer

im confused!

aripotta · Answer

point-slope form is y - y1 = m(x - x1)

anonymous · Answer

so would it be y = 3x + 1

aripotta · Answer

no

aripotta · Answer

3 isn't the slope

anonymous · Answer

y = 2x + 5

aripotta · Answer

y = 2x - 5

anonymous · Answer

Yay! thank you for your help! i got an A+....

aripotta · Answer

great! :) hopefully you understand it better now

anonymous · Answer

yes i do! thank you!
