I believe the answer is 1848.
What’s the test about you didn’t put anything?
Answer:
Part 1: m = -7
Part 2: y = -7x -11
Part 3: 7x + y = -11
Step-by-step explanation:
Part 1
Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula
m = (y2 - y1) / (x2 - x1)
m = (-4 -3) / (-1 - -2) =
m = -7/1
m = -7
Part 2
Use the point-slope form equation to find the slope-intercept form
y - y1 = m(x - x1)
y - 3 = -7(x - -2)
y = -7(x +2) +3
y = -7x -14 +3
y = -7x -11
Part 3
Move the x and y to the same side of the equation
y = -7x -11
7x + y = -11
Answer:
The measurement of angle a is 42.5°
The measurement of angle b is 19.5°
Step-by-step explanation:
Angle a = a
Angle b = b
m < a + m < b = 62°
"m <" means "measurement of angle..."
m < a + m < b = 4m < a - 108°
Subtract m < a from both sides of the equation
m < b = 4m < a - 108° - m < a
Simplify
m < b = 3m < a - 108°
Substitute into original equation
3m < a - 108° + m < a = 62°
Add m < a + 3m < a
4m < a - 108° = 62°
Add 108° to both sides of the equation
4m < a = 170°
Divide both sides of the equation by 4
m < a = 42.5°
m < b = 62° - 42.5° = 19.5°
Hope this helps :)
