Step-by-step explanation:
Let the equation of the line be y = mx + c
since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.
therefore, m = -1/2
sub (-4, -1):
-1 = -1/2(-4) + c
c = -3
therefore equation of the line is y = -1/2x - 3
This question demands knowledge on coordinate geometry's slope intercept form and finding unknowns. If you would like to venture further, you can check out my Instagram page (learntionary). Thanks!
This problem can be solved via a simple ratio and proportion approach. The concept is, the ratio of the actual length to the model length is constant. The solution is as follows:
Actual/Model = 12 m/ 1 cm = x/7.25 cm
Solve for x,
x = 87 m
<em>So, the actual distance is 87 m.</em>

Answer:
y = 5x - 13
Step-by-step explanation:
Slope of the line 5x + y = 2
Since, required line is parallel to the given line.
So, slope of required line = 5 (Parallel lines have same slope)
y - (- 3) = 5(x - 2)
y + 3 = 5x - 10
y = 5x - 10 - 3
y = 5x - 13
