What is an equation of the line, in pointslope form, that passes through the given points and has the given slope?
pont:(8,8);slope:3
y8=3(x+8)
y+8=3(x+8)
y8=3(x8)
y+8=3(x8)

Best ResponseYou've already chosen the best response.0this one easier than the last, since they gave you the slope to being with

Best ResponseYou've already chosen the best response.0\[yy_1=m(xx_1)\] with \[x_1=8,y_1=8\] remember the sign comes with the number

Best ResponseYou've already chosen the best response.0no are you getting the x's confused with the y's?

Best ResponseYou've already chosen the best response.0i can see it is a bit confusing because they use the point \((8,8)\) plug in \(x\) for \(x_1\) and \(8\) for \(y_1\) in \[yy_1=m(xx_1)\]

Best ResponseYou've already chosen the best response.0oops i meant "plug in \(8\) for \(x\)"

Best ResponseYou've already chosen the best response.0remember that x comes before y in the alphabet, just like it does in \((x,y)\) course you have to sing that whole song until the end

Best ResponseYou've already chosen the best response.0the "point slope" formula for a line, with slope \(m\) and point \((x_1,y_1)\) is \[\huge yy_1=m(xx_1)\]

Best ResponseYou've already chosen the best response.0\(x\) and \(y\) are variables, they stay in the answer \(x_1\) and \(y_1\) are numbers

Best ResponseYou've already chosen the best response.0you have in this case \[x_1=8,y_1=8,m=3\] so we plug them directly in to the formula, remembering that the minus sign that is in front of the number stays there

anonymous

Best ResponseYou've already chosen the best response.0i will plug them directly in :\[y(8)=3(x8)\]

anonymous

Best ResponseYou've already chosen the best response.0then you see that \((8)=+8\) so in the end you get \[y+8=3(x8)\]
