Answer:

m = 3/5

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step 1: Find 2 coordinates

(0, 80)

(-50, 50)

Step 2: Find slope <em>m</em>

m = (50 - 80)/(-50 - 0)

m = -30/-50

m = 3/5

Really could use help here.

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 :

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