The slope of the line below is -2. Write the point-slope equation of the line

kipiarov [429]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y-y_{0}=m(x-x_{0})$

Where:

m: It is the slope of the line

$(x_ {0}, y_ {0})$ : It is a point through which the line passes.

We have to:

$m = -2$

Thus, the equation is of the form:

$y-y_{0}=-2(x-x_{0})$

We substitute the point $(x_{0}, y_{0}) :( 4, -6)$

$y-(-6)=-2(x-4)\\y+6=-2(x-4)$

Finally, the equation is:

$y+6=-2(x-4)$

Answer:

$y = -2x + 2$

$y+6=-2(x-4)$

8 7 / 8 + 9 13 / 16 what is this in a mixed number.

FinnZ [79.3K]

Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16
