PART $1.$

Using the definition $of$ derivative $of$ a function $at$ a point, $f^{\text{'}}(a)=\underset{h0}{lim}\frac{f(a+h)-f(a)}{h},$ find the slope $of$ the tangent $to$ the curve $at$ the given point.

$f(x)=11x^2-6x-8$;$a=-2$

The slope $of$ the tangent $to$ the curve $ata=-2is$

Note: Enter a numerical value for the slope.

PART $2.$

The equation $of$ the line tangent $to$ the curve $ata=-2is$

Note: Type answer $in$ form $y=mx+b.$
