Answer:

\frac{12}{63} \: and \:  \frac{14}{63}

Step-by-step explanation:

The lowest common multiple between 21 and 9 is 63 as 21 = 21, 42, 63

9 = 9, 18, 27, 36, 45, 54, 63

therefore the common denominator is 63

\frac{4}{21}  =  \frac{?}{63}

21 × 3 = 63, so do the same to the numerator.

4 × 3 = 12 the numerator is 12

\frac{4}{12}  =  \frac{12}{63}

let's do the same to 2/9

\frac{2}{9}  =  \frac{?}{63}

9 × 7 = 63, so do the same to the numerator.

2 × 7 = 14

the numerator is 14

\frac{2}{9}  =  \frac{14}{63}

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The graphs can be described as shown below.

A.) The first graph has the y-intercept at 2. Therefore, the first graph can be described by the equation, y =5x + 2.

B.) For the second graph, the graph passes through the point (-1,0). Therefore, if we substitute the value of y as 0 in the equation y=3x+3, we will get x=-1.

Hence, the equation of the second graph is y=3x+3.

C.) For the third graph, the graph passes through the point (-1.5,0). Therefore, if we substitute the value of y as 0 in the equation y=2x+3, we will get x=-1.5.

Hence, the equation of the second graph is y=2x+3.
