Please help and explain. I am very confused and frustrated.

Answer:
slope = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
To calculate the slope m use the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 5 ) ← 2 points on the line
m = [tex]\frac{5-2}{4-0}[/tex] = [tex]\frac{3}{4}[/tex]
