Question

find the equation of a straight line which makes double of x intercept and triple of y intercept of the intercepts made by the line 4x+5y=20 on the axes​

Answer 1

Answer:

y= -6/5x + 12

Step-by-step explanation:

4x+5y=20

     5y= -4x+20

       y= -(4/5)x+4

Using this to find the x,y intercepts,

(5,0) as x intercept

(0,4) as y intercept

For the new line,

(10,0) as x' intercept

(0,12) as y' intercept

Plugging this in the the slope equation,

(10-0)/(0-12)= -6/5

Substituting 12 as y intercept,

y= -6/5 x + 12
