The equation of the straight line that passes through the points (0,0) and (1,4) is, a) y = 3x + 2
b) y = -x + 4
c) y = -4x + 2
d) y = 4x

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 =

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

m = = 4 , thus

y = 4x → d

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
