To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;
Given that
Testing Option A
Substitute and

<em>In both cases, the expression on the right hand side equates to that on the left hand side; </em>
<em>Hence, there's no need to check for other options. </em>
The parallel line to y = x + 3 and passes through
the point (0 , 4) is y = x + 4
Step-by-step explanation:
Parallel lines have:
1. The same slopes
2. The different y-intercept
The slope-intercept form of the linear equation is y = m x + c, where
m is the slope of the line and c is the y-intercept
We need to find the equation of the line that is parallel to
y = x + 3 and passes through the point (0 , 4)
∵ The two lines are parallel
∴ Their slopes are equal
∵ The equation of the given line is y = x + 3
∵ The form of the equation is y = m x + c
∴ m =
∴ The slope of the line is
∵ The equation of the line is y = mx + c
∵ m =
∴ The equation of the line is y = x + c
- To find c substitute x and y in the equation by the coordinates of
a point lies on the line
∵ The line passes through the point (0 , 4)
∴ x = 0 , y = 4
∴ 4 = (0) + c
∴ c = 4
∴ The equation of the line is y = x + 4
The parallel line to y = x + 3 and passes through
the point (0 , 4) is y = x + 4
