Answer:

slope(m)=6

Step-by-step explanation:

(2 , -1)=(x1 , y1)

(3 , 5)=(x2 , y2)

use formula : y2 - y1/x2 - x1

=5-(-1)/3-2

=5+1/1

=6/1

therefore slope of a line is 6.

What is the slope and y intercept of y=-7x+12

Hi there!

So the format of slope-intercept form is:

y= mx+b

m= your slope
x = just a variable
b= your y- intercept

Using those hints, see if you can figure out the answer! :)

Hope this helped!

What is the value of

Len [333]

$n-2=10n+42\qquad\text{add 2 to both sides}\\\\n=10n+44\qquad\text{subtract 10n from both sides}\\\\-9n=44\qquad\text{divide both sides by (-9)}\\\\\boxed{n=-\dfrac{44}{9}}$
