Let's solve for x:

2x+7y=−5

Step 1: Add -7y to both sides.

2x+7y+−7y=−5+−7y \\ 2x=−7y−5

Step 2: Divide both sides by 2.

\frac{2x}{2}  = \frac{7y−5}{2}\\ x=  \frac{ - 7}{2}  y+ \frac{ - 5}{2}

Therefore, the answer for the first one will be x = -7/2 y + -5/2.

Let's solve for x.

5x−7y=14

Step 1: Add 7y to both sides.

5x−7y+7y=14+7y \\5x=7y+14

Step 2: Divide both sides by 5.

\frac{5x}{5} = \frac{7y + 14}{5} \\ x= \frac{7}{5} y+ \frac{14}{5}

Therefore, the answer for the second one will be x = 7/5 y + 14/5

What is the slope of the line through (-9, 6) and (-3, 9)?<br> Choose 1 answer:
trasher [3.6K]

Given: Points (-9, 6) and (-3, 9)

Find:  The slope of the line that goes through those two points

Solution: In order to find the slope of the line that goes through the points that were provided we have to use the slope formula.  This formula subtracts the y-coordinates from each other and also the x-coordinates from each other to determine the rise/run which would give us the rate of change.

<u>Plug in the values</u>

  • m = \frac{y_2 - y_1}{x_2 - x_1}
  • m = \frac{9 - 6}{-3 - (-9)}

<u>Simplify the expression</u>

  • m = \frac{3}{-3 + 9}
  • m = \frac{3}{6}
  • m = \frac{1}{2}

Therefore, looking at the given options we can see that the best fitting one would be option A, 1/2.
