This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 410 and 70 using

GCF(410,70) = 10

410÷1070÷10=417

Can someone help me with the question please
alexandr1967 [171]

Answer:

Purple line: 4

Red dashed line: 2

Blue line: 1/2

Step-by-step explanation:

The purple line is the steepest line, therefore it has the biggest constant of proportionality or slope. Since 4 is the biggest number among the others, we attribute it to the purple line (the one with the point C on it).

Think of it this way:

y = ax+b \\

here b = 0 so y = ax

The greater a is, the greater y is. So for any value of x, y will be become bigger and bigger if we increase the value of a.

Take for example this one:

y = 2x \\

Take x=2\\ therefore y =4

Now take y = 4x and take x =2 therefore y = 8

When we increased this constant of proportionality, as you can see from 2 to 4, the value of y increase from 4 to 8.

Hope this is helpful. Think of it really carefully, and I'm sure you'll grasp the concept.
