Find the slope of the following graphs. ( even if you could just help describe what I need to do that would be great, I have no idea where to even start!)

Answer:
A
Step-by-step explanation:
to calculate the slope m of a line use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 2) ← 2 points on the line
m = [tex]\frac{2-0}{3-0}[/tex] = [tex]\frac{2}{3}[/tex] → A
