What is the equation of the line, in point slope form, that passes through the given point and has the given slope? point: (8,8) and slope 3
a. y8=3(x+8)
b. y+8=3(x+8)
c. y8=3(x8)
d. y+8=3(x8)
What are the intercepts of the equation?
5x+3y=15
what is the equation of the line perpendicular to the line y= 4/9 x  2 that passes through point (4,3)
a. y= 4/9 x 2
b. y= 9/4 x + 6
c. y= 9/4 x + 12
d. y= 9/4 x  12
i really need help, please help

Best ResponseYou've already chosen the best response.0wait so for y(8) how woould i distribute that, would it be just be 8y?

Best ResponseYou've already chosen the best response.0so it would be 8y= 3x  () 24?

Best ResponseYou've already chosen the best response.2question 2 intercepts to find the xintercept we let y=0 to find the yintercept we let x=0 but first we solve the given equation.. 5x+3y=15 lets solve for y 3y=155x y=(5x+15)/3 now find the x intercept.... 0=(5x+15)/3

Best ResponseYou've already chosen the best response.0you took the 3 away from y to solve for it butbwhy did you put it into the equation to divide. dont we cancel something out?

LynFran

Best ResponseYou've already chosen the best response.2since the 3 was being multiplied to y....3y ...to get the y term alone we divide by 3...and since its an equation...what we do to the left side we must do the same to the right side ...

Best ResponseYou've already chosen the best response.2so wats the xintercept?

LynFran

Best ResponseYou've already chosen the best response.20*3=(5x+15)/3*(3)...the 3 will cancel on the right side 0=5x+15 0+5x=5x+5x+15 5x=15 x=15/5 x=3 the xintercept (3,0)

Best ResponseYou've already chosen the best response.0okay i understand it better i guess its still a little confusing but ill look over some more later

Best ResponseYou've already chosen the best response.2lets solve the yintercept y=(5(0)+15)/3 y=(0+15)/3 y=15/3

LynFran
