Question

F(x) = x + 5y = 20
Assume that y is a function of x.

Answer 1

The equation is a linear equation in two variables, x and y, and can be rewritten in slope-intercept form as y = (-1/5)x + 4. Therefore, y is a function of x, where the slope of the line is -1/5 and the y-intercept is 4.

Answer 2

Explanation:

Then re-arranging

f(x) = y = - 1/5x + 4 <=====this is the equation of a line slope = -1/5 and y axis intercept = 4
