Question

The y-intercept if the constant of proportionality is 0.2 is

  1. 0.2
  2. 2
  3. 5
  4. 0

hintHint:

Use the formula of constant of proportionality to find the formula. Remember, x is equal to zero at y-intercept.

The correct answer is: 0


    G i v e n comma
C o n s tan t space o f space p r o p o r t i o n a i t y space equals space k space equals space 0.2

T o space f i n d comma
y minus i n t e r c e p t

W e space k n o w space t h a t comma space f o r space y minus i n t e r c e p t comma space x equals 0

y space equals space k x
y space equals space open parentheses 0.2 close parentheses open parentheses 0 close parentheses
y space equals space 0

    The sum of both the intercepts in the equation 4x + 2 = y is

    A y-intercept is a point where the graph of a function or relation intersects with the y-axis of the coordinate system. To find the y-intercept, set x = 0 and solve for y.

    An x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system. To find the x-intercept set y = 0 and solve for x.
