What is the equation of a line that passes through the points (3,6) and (8, 4)?

Dahasolnce [82]

Step-by-step explanation:

slope=4-6/8-3=-2/5

chosing another point (x,y) we have

y-4/x-8= -2/5

y-4=-2/5(x-8)

y= -2/5x+16/5+4

I need to know the answer please…

Answer is a= 51/7 or 7 2/7

Step by step

-2/3 (a + 3) = 5/3a - 19

Distribute to resolve parentheses

-2/3a -2 = 5/3a - 19

Now to move variables to one side
Add 2/3a to both sides

-2/3a + 2/3a -2 = 5/3a + 2/3a -19

Combine like terms

-2 = 7/3a -19

Add 19 to both sides to isolate variable

-2 +19 = 7/3a -19 + 19

17 = 7/3a

Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)

17 * 3/7 = a

51/7 = a
