    no you have it backwards m=slop B=y-intercept

    b is not your slope and m is not the y intercept. you have that backwards.

    m is the slope and b is the y intercept

    f() = y The f() is a function but the so your points are (-7,-1) (1,1) (5.2) slope = m = \( \frac{Y_1-Y_2}{X_1-X_2} \) slope =\( \frac{1}{4} \) Now take any point and use the point slope form and plug in one of the points \( y - y_1 = m(x - x_1) \) \( y - 1 = m(x - 1) \) Are you still with me and see what I am doing?

Times it all by 4. \( 4(y - 1) = 4(\frac{1}{4}(x - 1)) \) \( 4y - 4 = 4x - 4 \) Now put it in slope intercept form \( 4y - 4 = 4x - 4 \) \( 4y - 4+4 = 4x - 4 +4 \) \( 4y = 4x \) \( \frac{4y}{4} = \frac{4x}{4} \) \( y = 4x \) The y intercept is at 0
