Answer:

3. 10 - 5 is 5. so that is the difference. difference means subtraction.

4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78

5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.

6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130

Write an equation in standard form of the line that passes through the given point and the given slope. (-9, -4); m = -1/3

tigry1 [53]

<h2>Answer:</h2>

First, we must determine b using slope-intercept form*, the given point, and the given slope.

$-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b$

Second, we need to set up the equation of the line in slope-intercept form.

$y = -\frac{1}{3}x - 1$

Third, we convert the above equation to STANDARD FORM**.

$y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1$

We now have our equation: $\frac{1}{3}x - y = -1$

*Slope-intercept form: y = mx + b

**Standard form: ax + by = c
