Really could use help here.
marishachu [46]

Answer:

\mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}

Step-by-step explanation:

<u>Finding the unit rate of the graph</u> :

  • Take 2 points and find the slope
  • ⇒ (0,0) and (12, 25)
  • ⇒ m = 25 - 0 / 12 - 0
  • ⇒ m = <u>25/12</u>
  • The equation is : <u>y = 25/12x</u>

Now, the equations with greater unit rates (in increasing order) are :

  • \mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}
