A toddler takes off running down the sidewalk at 270 ft/min. One minute later, a worried mother runs after the child at 580 ft/min. After how many minutes will the mother overtake the toddler?

Answers

Answer 1
Answer: we know that in one minute the toddler is 2(270)=540 feet and mother is 580 so less than 1 minute

Slope point form:
We need the slope "m" and a point (x₀,y₀)
y-y₀=m(x-x₀)


1)
we calculate the slope "m".
Given two points:
(x₁,y₁)
(x₂,y₂) 
the slope "m" is:
m=(y₂-y₁) / (x₂-x₁)

In this case:
(4,10)
(6,11)
m=(11-10) / (6-4)=1/2

Now, we calculate the solpe point form.
(4,10)
m=1/2

y-y₀=m(x-x₀)
y-10=(1/2)(x-4)

we make the standard form
y-10=x/2 - 2

-x+2y=-4+20
-x+2y=16

Answer:  -x+2y=16

Find the point-slope equation for the line that passes through the points (5,35) and (-6,-31). Use the first point in your equation.

Final answer:

The point-slope equation of a line can be found by calculating the slope and substituting the values into the point-slope formula. For the given points (5,35) and (-6,-31), the equation becomes y - 35 = m(x - 5).

Explanation:

The point-slope equation of a line, also known as the slope-intercept form, is given by the formula y - y1 = m(x - x1), where m represents the slope of the line and (x1, y1) represents the coordinates of a point on the line.

To find the equation for the line passing through the points (5,35) and (-6,-31), we can use the following steps:

  1. First, calculate the slope using the formula m = (y2 - y1) / (x2 - x1).
  2. Next, substitute the values of the slope (m) and one of the points ((x1, y1)) into the point-slope equation.
  3. Simplify the equation to get the final point-slope equation.

Using the point (5,35) as our reference, we can substitute x1 = 5 and y1 = 35 into the equation: y - 35 = m(x - 5).
