Find the equation of the straight line which passes through the point (-1,3) and make intercept on x - axis as thrice that on y - axis .​

Step-by-step explanation:

Given

Required

Determine the equation

First, we calculate the intercepts using:

Where

b = Intercept on y axis.

a = Intercept on x axis.

From the question:

The equation becomes:

Multiply through by 3b

We have:

So:

Make b the subject

Substitute in to get the equation

Make 3y the subject

Make y the subject

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
