Answer:

slope = 4

Step-by-step explanation:

(70,20)

(80,60)

slope = rise over run = (y2-y1)/(x2-x1)

(60-20)/(80-70) = 40/10 = 4

The slope is how much it’s going up by each time (rate of change)
Notice at x = 70, y = 20
And at x = 80, y = 60
Use slope formula
(y2- y1)/(x2-x1)
(60-20)/(80-70) = 40/10 = 4
Therefore, the slope is 4

Which line shows the first error in the solution?
andrew11 [14]
<h3>Answer:</h3>

The first line.

<h3>Step-by-step explanation:</h3>

If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.

Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.

_____

The solution should be ...

... x/3 = 4 + (-11)

... x = 3·(-7)

... x = -21

___

<u><em>Check</em></u>

-21 divided by 3 is -7. That is 4 more than -11.
