1

Understand the problem

For the following straight line equation, state what is the rate of change?

y=14x+8 y=\frac{1}{4}x+8

Step-by-step solution

To determine the rate of change for the given line equation y=14x+8 y = \frac{1}{4}x + 8 :

  • The equation is in the slope-intercept form, y=mx+b y = mx + b , where m m represents the slope or the rate of change.
  • By comparing the given equation y=14x+8 y = \frac{1}{4}x + 8 with the general form y=mx+b y = mx + b , we see that the slope m m is 14 \frac{1}{4} .
  • The rate of change for this line, thus, is 14\frac{1}{4}.

Therefore, the rate of change for the line is 14 \frac{1}{4} .
