33+9=42. 42-40=2. These simple calculations show that two people must have raised there hands for both because the sum of the two groups who raised hands is two more than the amount of people in the actual class
Answer:
50 degrees
Step-by-step explanation:
Answer:
y= -3
y= 2
y= 5
Step-by-step explanation:
replace the x in the equation with the numbers in the table
If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)
y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10
y = 5x + 11
Make it y = mx + b form
4y = -2x + 8
Divide by 4
Y = -1/2x + 8
The slope is -1/2
