ABOUT THIS FORMULA:

  • <u>Y2 - Y1</u>

        X2 - X1

FOR PROBLEM: (2, 1) & (0, -5)

  • Y2 is -5
  • Y1 is 1
  • X2 is 0
  • X1 is 2

ABOUT POINT SLOPE FORM:

  • y - Y1 = m(x - X1)
  • Y1 & X1 is a point
  • m represents the slope
  • This form allows you to identify the slope & the point on the line

ABOUT SLOPE INTERCEPT FORM:

  • y = mx + b
  • m represents the slope
  • b represents the y - intercept AKA the starting point

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 1</u>

0 - 2

<u>-6</u>

-2

SIMPLIFIED: -3 because both -6 & -2 can be divided by 2.

y - Y1 = m(x - X1)

y - -1 = -3(x - 2)

y + 1 = -3x + 6

   - 1           - 1

y = -3x - 5 --- SLOPE INTERCEPT FORM


I do not see y = -3x - 5 as one of your answer choices.... So, I am sorry if I am incorrect...

Given the graphs of y = f(x) and y = g(x), what is the value of f(x)-g(x) where the two graphs intersect?
inysia [295]

Answer:

0

Step-by-step explanation:

If they want the values of where the graphs intersect, that means the values are both = to each other, meaning subtracting the same value by the same value is 0
