Question

suppose y varies directly with x, and y=11 when x= -4. What direct variation equation relates x and y? What is the value of y when x=2?

Answer 1

@helpmeplease656 Let's see...
\[y=kx\]Since y varies directly to x. We can say that:
\[\frac{ y }{ 11}=\frac{ 2 }{ -4 }\] After cross multiplication, we can say that:
\[y=\frac{ -11 }{ 2 }\]
