Answer:

Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>

Where:
is the slope
and
are corresponding coordinate points 
Insert the given values:

Solve for y. Expand the right sie using the distributive property:

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>

Where:
is the slope
is the y-intercept
and
are corresponding coordinate points 
Insert the given values:

Simplify the multiplication:

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

:Done
It results in -2x because 1+1=2 and its the same with negative numbers

Answer:
[211.43,216.57]
Step-by-step explanation:
1.2% of 214 is ...
0.012 × 214 = 2.568 ≈ 2.57 . . . . rounded to hundredths
Then the minimum possible value is ...
214 -2.57 = 211.43
and the maximum possible value is ...
214 +2.57 = 216.57
The range is 211.43 to 216.57.
Answer:
