Answer:
y= -1/2x+3
Step-by-step explanation:
as it is parallel the slope/gradient is the same: -1/2x
then substitute the values 4 and 1 in the equation of a straight line y= mx +c
therefore it becomes: 1= -1/2×4+c
and then u will get c
then at the end remember to write the whole equation: y= -1/2x+3
