Question

Given the point (3, 4) and the slope of 6, find y when x = 27
help!!

Answer 1

Sorry my OpenStudy crashed :( I need to retype all of that. Grr

Answer 2

We can use the Point-Slope form of a line:\[\Large y-y_o=m(x-x_o)\]

We were given the slope:\[\Large m=6\]And a starting point,\[\Large (x_o,y_o)=(3,4)\]And an x value,\[\Large x=27\]

Answer 3

We can plug all those pieces in and solve for y! :O

Answer 4

so y= 6x+4?

Answer 5

Hmm you didn't plug in the x=27.
And it looks like you did something wrong in there :[

Let's see...
Plugging in our values gives us,\[\Large y-y_o=m(x-x_o) \quad\color{orangered}{\to}\quad y-4=6(27-3)\]

Answer 6

y= 163?

Answer 7

27 minus 3,
\[\large y-4=6(24)\]
6 times 24,\[\large y-4=144\]Add 4 to each side,\[\large y=144+4\]
