It helps to know the definition of a linear function, which is just a straight line, like y=x
So, isolate 3y which means
3y=4x+20
Divide by 3 on both sides and you have
y=4x/3 + 20/3
If you graph it, the function gives a straight line, so therefore it is a linear function.
So, isolate 3y which means
3y=4x+20
Divide by 3 on both sides and you have
y=4x/3 + 20/3
If you graph it, the function gives a straight line, so therefore it is a linear function.
The slope is constant for the given function thus it will be a linear function.
What is a linear function?
A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function always has the same and constant slope.
Given the function
3y - 4x = 20
3y = 20 + 4x
y = (4/3)x + (20/3)
The general equation of linear function is
y = mx + c , where m is the slope.
By comparing both
Slope = 4/3 which is a constant.
Since the slope of the line is constant hence given line will be a linear function.
