    the slope of a line is y2 -y1 / x2 -x1 i will pick x1 = 0 and x2 = 2 The slope becomes -2 - (-2) / 2-0 = 0/2= 0 zero slope which is answer d.

    its zero, I'm not too sure how I can explain this properly, but for horizontal lines, the slope is always zero

    formula to find slope \[\huge\rm \frac{ y_2-y_1}{ x_2-x_1 }\] since the line is horizontal |dw:1443791506934:dw| horizontal line when y is constant and x values are changing

    let's say we have (2,3)(4, 3)( notice y values are the same ) plugin \[\frac{ 3-3 }{ 4-2 }\] when you subtract same numbers what would you get in this question 3-3 =?

    remember the formula is = change in y's over change in x's

    alright just practice remember when we subtract same numbers we will get zero so zero divided by anything would be just 0

    let's say if we have vertical line |dw:1443791845577:dw| in this questions x value would stay the same

    so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\]

    alright so \(\color{blue}{\text{Originally Posted by}}\) @Nnesha so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\] \(\color{blue}{\text{End of Quote}}\) solve this

    no no you can't divide by zero whenever u get `0 at the denominator ` answer would be undefined bec you can't divide by 0
