Question

The equation of the line given in the following graph is:

• A. $y=7x$
• B. $y=\frac{7}{x}$
• C. $y=\frac{7}{x}+1$
• D. $y=7+x$

Answer 1

The correct option is A

$y=7x$

Points on the line : (0,0), (1,7), (2, 14)

Comparing the x and y coordinates of each point, we find:

$PointXY$
$(0,0)0⟹0\times 7⟹0$
$(1,7)1⟹1\times 7⟹7$
$(2,14)2⟹2\times 7⟹14$

Hence, for every given point, the value of y coordinate is 7 times that of the x coordinate.

Therefore, the equation of the given line is y = 7x
