3x + 2y= 9. How do I solve this problem?

1 answer:

3 0

All you can do to solve this is isolate the y
3x+2y=9 (subtract 3x from both sides)
2y=9-3x (divide both sides by 2)
y=9/2-3/2x or y=-3/2x+9/2

Hope this helps

What is the slope of the line passing through the points (−1, 3) and (4, −7) ?

alexira [117]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

in this problem we have

$A(-1,3)\ B(4,-7)$

substitute in the formula

$m=\frac{-7-3}{4+1}$

$m=\frac{-10}{5}$

$m=-2$

therefore

<u>the answer is the option A</u>

$m=-2$
