Value of r is -4

Step-by-step explanation:

We are given points (-1,-6) and (0,r) on line and slope of line is -2. We need to find value of r.

Using slope formula when two points are given:

Slope=\frac{y_2-y_1}{x_2-x_1}

Where x_1=-1,\,\,y_1=-6,\,\,x_2=0,\,\,y_2=r

Putting values:

2=\frac{r-(-6)}{0-(-1)} \\2=\frac{r+6}{0+1} \\2=\frac{r+6}{1} \\2=r+6

Adding -6 on both sides:

2-6=r\\-4=r

So, Value of r is -4

The best thing I can think of is
((2)(4))(.5+1)=(2)(6)
because (2*4)(1.5)= 8*1.5
= 12
and 2*6 =12
and 12=12

I hope this is right and I hope it helps!
