“Find the equation of the line passing through (8,-2) & (7,-4). Write your equation in point-slope AND slope intercept forms
MakcuM [25]
We know that
the equation of the line in point-slope------------> <span> (y – y1) = m(x – x1)
</span>the equation of the line in slope intercept forms. ----->  y =mx+b

find the slope m
point <span>(8,-2) & (7,-4).
m=(y2-y1)/(x2-x1)---------> </span>(-4+2)/(7-8)=-2/-1----------> m=2

Part A)
find the equation of the line in point-slope using <span>(8,-2)
</span>(y – y1) = m(x – x1)---------> (y-(-2)) = 2*(x – 8)-------> y+2=2x-16
<span>y=2x-16-2--------> y=2x-18

</span>Part B)
find the equation of the line in point-slope using (7,-4)
(y – y1) = m(x – x1)---------> (y-(-4)) = 2*(x – 7)-------> y+4=2x-14
y=2x-14-4--------> y=2x-18<span>

</span>Part C)
find the equation of the line in slope intercept forms
using (7,-4)
y=mx+b--------> -4=2*7+b----------> -4=14+b-----------> b=-18
then
y=2x-18

Part D)
find the equation of the line in slope intercept forms
using (8,-2)
y=mx+b--------> -2=2*8+b----------> -2=16+b-----------> b=-18
then
y=2x-18

Find the slope of the line between (1,5)and (3,9)
Volgvan
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).

Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2

Slope is 2.

Please help due in 2 min <br> and I can't get another one wrong
ycow [4]

Answer:

True

Step-by-step explanation:

Both functions are straight lines. This means they will continue in both directions forever. So the both have a range and domain of all real numbers. Linear functions commonly have range and domains of all real numbers.
