Answer:
y = 2x + 4
Explanation:
the equation of a line in point- slope form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 and passes through point (0, 4 ) ⇒ c = 4
y = 2x + 4 ← equation of line
General form of linear equation: y = mx + c
where m is the gradient and c is the y-intercept
Given gradient = 2
⇒ m = 2
⇒ y = 2x + c
y-intercept is when x = 0
Given (0, 4), so y = 4 when x = 0
⇒ c = 4
⇒ y = 2x + 4
