The equation of line is given by y = ( 4/3 )x + 7/3 , where the slope of the line is m = 4/3

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

3y - 4x = 7   be equation (1)

On simplifying the equation , we get

Adding 4x on both sides of the equation , we get

3y = 4x + 7

Divide by 3 on both sides of the equation , we get

y = ( 4/3 )x + 7/3

Now , it is expressed as y = mx + b where m is the slope and b is the y-intercept

Hence , the equation of line is y = ( 4/3 )x + 7/3
