Question

The equation of the straight line that passes through the points (0,0) and (1,4) is,

Answer 1

Answer:

D

Step-by-step explanation:

Please refer to picture attached.

The best method to deduce if the graph passes through the points mentioned, just substitute the values of x from the point into the equation to deduce if the y value is the same as the value in the point.

Answer 2

Answer:

d

Step-by-step explanation:

The equation of a line which passes through the origin is

y = mx ( where m is the slope )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 4)

m = $\frac{4-0}{1-0}$ = 4 , thus

y = 4x → d
