Slope formula: y2-y1/x2-x1

Question 1:

= 14-(-15)/1-(-11)

= 29/12

= 2 5/12

Therefore, the slope is 2 5/12 or 29/12.

Question 2:

= 12-(-19)/-9-16

= 31/-25

= -31/25

= 1 6/25

Therefore, the slope is 1 6/25 or -31/25.

Question 3:

= -3-(-3)/8-(-18)

= 0/26

Therefore, the slope is 0.

Best of Luck!

$y=2x \newline y= x^{2} -3$

Substitue 2x for y in the second equation:

$2x= x^{2} -3$

Rearrange to $a x^{2} +bx+c=0$ form:

$x^{2} -2x-3=0$

Factor:

$(x-3)(x+1)=0$

Zeros are $x=3$ and $x=-1$

To find y-coordinates of pts of intersection, plug these x-values into first equation to get $y=-2$ and $y=6$
