Answer:

y=-2x+8

Step-by-step explanation:

y+2=-2(x-5) Given

Answer:

y = -2x + 8

About Point Slope Form:

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

About Slope Intercept Form:

  • y = mx + b
  • b is the y-intercept
  • m is the slope

Problem:

y + 2 = -2(x - 5)

y + 2 = -2x + 10

   -2            -2

y = -2x + 8

If y=4 when x=12, find y when x=-24
goldfiish [28.3K]

The value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.

<h3>What is a proportional relationship?</h3>

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

The question is incomplete.

The complete question is:

If y varies directly with x, and If y = 4 when x = 12, how do you find y when x = -24?

y ∝ x  (given)

y = kx

k is the constant of proportionality.

4 = 12k  (y = 4, and x = 12)

k = 1/3

y = x/3

Plug x = -24

y = -24/3

y = -8

Thus, the value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.
