Question

Plz plz plz help on number 6,7,8,9 I would greatly appre and whoever gets it get brainliest

Answer 1

6: Yes, it is linear. The constant rate of change is $\frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }$, which you can make $\frac{175-100}{10-5}$. This simplifies to 15, so the constant rate of change is 15.

7. Yes, a proportional relationship exists because every output value is exactly three times every corresponding input value.

8. Yes, a proportional relationship exists because every output value is exactly $\frac{3}{8}$ times the corresponding input value.

9. Yes, a proportional relationship exists because every y value is 7.5 times every corresponding x value, and if a line were to be drawn through the points, it would go through the origin (0,0).
