To find the slope, we use two points from the table (-3, 1.5) and (0,3).-
Now, we use the slope formula
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
Replacing the points, we have
![m=(3-0.5)/(0-(-3))=(2.5)/(3)=((5)/(2))/(3)=(5)/(6)](https://img.qammunity.org/2023/formulas/mathematics/college/9yr53dpybgh7gcw18gjiue4ocy4jxzzzgh.png)
The slope is 5/6.
On the other hand, the starting point refers to the initial condition or the y-intercept which is given by the point (0,3).
Therefore, the starting point is 3.
At last, the equation would be
![y=(5)/(6)x+3](https://img.qammunity.org/2023/formulas/mathematics/college/3w53uvatci9zb70cltbw9tfaigd0i95r35.png)
Remember that the slope must be a coefficient of x, and the starting point is the independent term.
