    Finding the slope and y-intercept

    11. State whether each function is linear or non-linear. If the function is linear, identify its slope and y-intercept.

    a. y=5x-2
    b. y=x^2
    c. x=4y

    My teacher kinda skipped on how to find the slope and the x/y-intercept of a function, and I couldn't really find a proper lesson. Can anyone explain?

    For y = mx + c:

    m is the slope.

    c is the y-intercept

    Hello
    A. Yes
    slope is 5/1 and y intercept is -2
    B. No
    C. Yes
    slope is 1/1 and y intercept is 0

    Ax+By=C
    A. you woul have to subtract -5x to the left side to see if it makes the equation and it did.
    B. it did not make the equation because when you take x2 to the left side x was squared and it needs to be the power of one.
    C. subtract -4y to the left. then u have x-4y=0 then divide -4 from y and 0. that leaves u with x+y=0
