Answer:
Sorry. What's the question?
Answer:
<h2>
y-9 = 17(x+7)</h2>
Step-by-step explanation:
Given the points (-8, -8) and (-7, 9), the general form of equation of the line passing through this point is expressed as y-y1 = m(x-x1) where;
m = slope or gradient and (x1, y1) is the point
m = Δy/Δx = y₂-y₁/x₂-x₁
m = 9-(-8)/-7-(-8)
m = 17/1
m = 17
The slope of the line is 17.
The point-slope equation of the line through the point (-7, 9) is expressed as
y-9 = 17(x-(-7))
y-9 = 17(x+7)
Answer:
9/4 = 2.25 and 3/5=.6
Step-by-step explanation:
9/4 also equals 2 1/4'
Answer:
y - 3 = 
(x - 1)
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (4 - 3) / (-1 - 1)
=
Point slope form:
y - y₁ = m(x - x₁)
y - 3 = (x - 1)
can be further simplify:
y - 3 = 
+ 
y - 7/2 = -1/2x
Answer:
9.16 minutes per mile
At 10 miles, she is short of her intended rate
Step-by-step explanation:
2 hours means 60 * 2 = 120 minutes
Randy aims to run 13.1 miles in 120 minutes. So to get the rate [min/mi], we must divide total minutes by total miles:
120/13.1 = 9.16 minutes per mile
Moreover, she realized at 10 miles, she has taken 90 minutes. So her rate at that point [min/mi] is:
90/10 = 9 min/mi
Well, Randy is short of her intended rate
