Question

Find the equation of a line having
x-intercept 8 and y intercept -4. [3]​

Answer 1

Answer:

x - 2y - 8 = 0

Step-by-step explanation:

x - itercept  = 8 ,  y-intercept = - 4

a = 8 ,  b = - 4

Using intercept form,  the equation of st. line

               x/a  + y/b  =  1

              x/8  + y/- 4   = 1

     multiply by 8 on bothsides

  x - 2y  = 8

∴   x - 2y - 8 = 0  is the required equation

Answer 2

Answer:

x+2y-8=0

Step-by-step explanation:

The x intercept is a coordinate point on the x-axis. The x-intercept is (4, 0).

The y-intercept is a coordinate point on the y-axis. The y-intercept is (0, 8).

slope = (y2 - y1) / (x 2- x1)

m=-1/2

equation of line = y-y1=m(x-x1)

=y-0=-1/2(x-4) or y-8=-1/2(x-0)

=x+2y-8=0
