Answer:
y = x + 4 or x - y + 4 = 0
Explanation:
The relation between "x" and "y" is linear.
Slope of the line m =
=
= 1
Coordinates of y-intercept of the line (0, b) = (0, 4)
Slope-intercept form of a line equation is y = mx + b
The rule (equation) of line is y = x + 4
or x - y + 4 = 0 (in standard form)
