Question

What is the slope of a graph of -14x + 7y = -9 ?

Answer 1

Answer: The slope is 2.

Explanation:

The equation of the line in slope-intercept form is:

`y=mx+b`

Where m is the slope and y is the y-intercept.

So, you can solve for y to rewrite the equation in the form shown above and obtain the value of the slope, as following:

`7y=14x-9\\y=(14)/(7)x-(9)/(7)\\y=2x-(9)/(7)`

Therefore, as you can see, the slope is:

`m=2`

Answer 2

2

Explanation:

The equation form that we need to arrange this to is
`y=mx+b`, where m will give us the slope.

Arranging:

`-14x+7y=-9\\7y=14x-9\\y=(14x-9)/(7)\\y=2x-(9)/(7)`

Hence, the slope is 2
