What is the slope of the line that passes through the points (1, 1) and (9, 7)? 3/4 4/5 5/4 4/3

3/4

Step-by-step explanation:

We can use the slope of the line by using the slope formula

m = (y2-y1)/(x2-x1)

   = (7-1)/ ( 9-1)

    = 6/8

    = 3/4

3/4

Step-by-step explanation: To find the slope of this line, I will be showing you the graphing method.

To find the slope of the line using the graphing method,

we first set up a coordinate system.

Next, we plot our two points, (1, 1), which we label point A, and (9, 7), which we label point B, and we graph our line, as shown below.

Now, remember that the slope, or m, is equal to

the rise over run from point A to point B.

To get from point A to point B, we rise

6 units and run 8 units to the left.

So our slope, or rise over run, is 6 over 8, which reduces to 3/4.

y = x + 95

y = 42 + 95

y=137 mm hg

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
