Question

Write an equation of the line that is parallel to the line y = -x + 4 and passes through the points 0, 10.

Answer 1

Line parallel to y = -x+4 will have the same gradient.
Gradient = -1
Equation of line: y = -x + c
Point : (0,10) replace in the above equation
y = -x + c
10 = -0 + c
c = 10
Equation is: y = -x + 10
