Question

What is the y-intercept of the function f(x) = -2/3x + 1/3

-2/9
-1/3
1/3
2/9

Answer 1

1/3

Explanation:

`\text{The slope-intercept form of an equation of a line:}\\\\y=mx+b\\\\m-slope\\b-y-intercept\\\\\text{We have the equation:}\ f(x)=-(2)/(3)x+(1)/(3)\to y=-(2)/(3)x+(1)/(3)\\\\the\ slope:\ m=-(2)/(3)\\\\the\ y-intercept:\ b=(1)/(3)`
