Answer:
see explanation
Step-by-step explanation:
(a ) calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = A(0, 6) and (x₂, y₂ ) = B(3, 0 )
= 
= 
= - 2
(b)
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
(c)
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
(0, 6 ) is the y-intercept ⇒ c = 6
y = x + 6 ← equation of perpendicular line

Answer: Answer: x≥ −1
/2
Step-by-step explanation:
The equation in slope intercept form is 
Explanation:
The given pair of points are 
and 
The slope can be determined using the formula,
Substituting the points and in the slope formula, we have,
The equation in slope intercept form can be determined using the formula,
Substituting and the point in the above formula, we get,
Thus, the equation in slope intercept form is
Answer:
He volunteered 10 hrs 15 min on average.
Step-by-step explanation:
The first week: 8 hrs
The second week: 12 hrs
The third week: 12 hrs
The fourth week: 9 hrs
8 + 12 + 12 + 9 = 41 hrs total
41 hours/4 weeks = 10.25 hrs (10 hrs 15 min)
