Answer:

$\frac{2}{4}$

Step-by-step explanation:

Remember that in order to find the slope of two points you need to substitute the variables and subtract making sure you keep the 2's and the 1's together.

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

Plugin your numbers:

$=\frac{7-5}{9-5}$

Which order pair lies on the line 2x-y= -5

Lady bird [3.3K]

Answer:

Let's solve for x.

2x−y=−5

Step 1: Add y to both sides.

2x−y+y=−5+y

2x=y−5

Step 2: Divide both sides by 2.

2x/2=y-5/2

Answer:

x=1/2y+-5/2
