Question

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

answers:
a) 122
b)14
c)141
d)148

Answer 1

help plz

Answer 2

You should recognize the forumla for a slope:
\[y-y_0=k(x-x_o)\]

Answer 3

y - y1 = m(x - x1)
y - 4 = 6(x - 3)
y - 4 = 6x - 18
y = 6x - 18 + 4
y = 6x - 14

Now to find y when x = 27, just sub in 27 for x.
y = 6(27) - 14

I think you can handle it now

Answer 4

ya thx
