Question

Find the equation of the line.
the line passthrough (8, 4) and has the same x intercept as the line -4x+y=1 write in form y=mx+b

Answer 1

Find the x-intercept of -4x+y=1.

Let y = 0.

-4x + 0 = 1
-4x = 1

x = - 1/4

Now to find the equation of the line joining (-1/4,0) and (8,4) ....

Answer 2

The slope of the line is [ 0 - 4] / (-1/4) - 8] = (-4) / (-33/4) = 16/33.

Using the point (8,4), y - 4 = (16/33) (x - 8)

Answer 3

Multiply through by 33.

33y - 132 = 16(x - 8)

Answer 4

is it -4

Answer 5

33y - 132 = 16x - 128

Answer 6

33y = 16x + 4

Answer 7

y = (16/33) x + 4/33

Answer 8

That is the equation -- the answer.
