The constant term in the given equation is -3. This is the point where the graph must cross the y-axis. Graph B crosses at +3, so is not the answer.
The coefficient of x is 3/4. This means the line rises 3 units in 4 horizontal units. The line in Graph C appears to rise 3 units in 2 horizontal units, so is not the answer.
Graph A has the correct y-intercept and slope, so is the correct choice.
Starting from the y-intercept of [0, −3], the graph did <em>rise</em><em>\</em><em>run</em><em> </em>by moving either moving three blocks <em>south</em><em> </em>over four blocks <em>west</em><em>,</em><em> </em>or three blocks <em>north</em><em> </em>over four blocks <em>east</em><em> </em>[<em>west</em><em> </em>and <em>south</em><em> </em>are negatives].
Let, Harry's age - x then Nick is 7x. After 6 years, Harry is x+6 and Nick is 7x+6 So, 7x+6= 5(x+6)=> 2x = 30-6X = 12 In 6 years, Harry will be 12+6 = 18 years (Ans)
