\dfrac{3}{7} \div  \dfrac{2}{3} =  \dfrac{3}{7} \times  \dfrac{3}{2} =  \dfrac{9}{14}

1.2 \div 0.04 = 1 \dfrac{2}{10} \div  \dfrac{4}{100}  =  \dfrac{12}{10} \div  \dfrac{4}{100}   =  \dfrac{12}{10} \times  \dfrac{100}{4} = \dfrac{3}{1} \times  \dfrac{10}{1} = 30

8^\frac{2}{3} \div 4^ \frac{1}{2} =   2^{3 \times \frac{2}{3}} \div 2^{2\times \frac{1}{2} } =  2^2 \div 2^1 = 2^{2-1}  = 2

What are 2 points on the graph for 6x-5y=25
zepelin [54]
To find any two random point on the graph of 6x-5y=25, we can just plug in any two values for x and solve for y, and find the 2 points in the form of (x,y).

So lets plug in x=0.

\sf 6x-5y=25
\sf 6(0)-5y=25
\sf -5y=25
\sf y=-5
So one point is (0,-5)

And to find another point, we can plug in x=1

\sf 6x-5y=25
\sf 6(1)-5y=25
\sf 6-5y=25
\sf -5y=25-6
\sf -5y=19
\sf y=19/-5
\sf y=-3.8
So another point is (1,-3.8)
