If the , points on the graphs are (-4,1) and (2,1) what is the equation ?
balandron [24]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept


To find "m", you can use the slope formula and plug in the two points:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{1-1}{2-(-4)}

m=\frac{1-1}{2+4}

m=\frac{0}{6}=0


The slope is 0 so:

y = mx + b

y = 0x + b     [any number multiplied by 0 is 0]

y = b      

To find "b", you plug in either of the points into the equation (since both of their y values are 1]

y = b

1 = b


Your equation is:

y = 1      (This is a horizontal line)

12. Linda walks through a road. If her walking speed increases from 1 m/s to 1.5 m/s, she will complete the walk 200 s earlier.
Katen [24]

Answer:

<u>600 meters</u>

Step-by-step explanation:

<u>Case 1 : Speed of 1 m/s</u>

  • d = v * t
  • d = 1 * t
  • d = t       [Equation 1]

<u>Case 2 : Speed of 1.5 m/s</u>

  • d = v * t
  • d = 1.5 * (t - 200)
  • d = 1.5t - 300 [Equation 2]

As distance in both cases is the same, equate the values of d from both equations.

  • t = 1.5t - 300
  • 0.5t = 300
  • t = 300 * 2
  • <u>t = 600 s</u>

Now, put the value of t in <u>Equation 1</u> to find d.

  • d = <u>600 meters</u>
