I have no clue how to help my daughter with these

SOLUTION:
From the graph on question 1, the two identfying points are (-2,0) and (2,3)
[tex]\begin{gathered} \text{lets call it (x}_1,y_1)and(x_2,y_2) \\ slope\text{ m=}\frac{y_2-y_1}{x_2-x_1} \\ m=\text{ }\frac{3-0}{2-(-2)} \\ m=\text{ }\frac{3}{2+2} \\ m=\text{ }\frac{3}{4} \end{gathered}[/tex]Final solution
The slope of the line is 3/4.
(This interpretes as the for every step of 4 units to the right, there is a rise by 3 units)
