How do I find the equation of a line parallel to y=-1/2x +3 passing through (3,1/2) please help I’ve been here for a hour

Answer:

see explanation

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = -
(1)/(2) x + 3 is in this form

with m = -
(1)/(2)

• Parallel lines have equal slopes, hence

slope of parallel line = -
(1)/(2), thus

y = -
(1)/(2) x + c ← is the partial equation

To find c substitute (3,
(1)/(2)) into the partial equation


(1)/(2) = -
(3)/(2) + c ⇒ c = 2

y = -
(1)/(2) x + 2 ← equation of parallel line

If a line is parallel to the line, then the slope will remain the same

Now, you just need to substitute the values of that coordinate into the equation

1/2 = -1/2(3) + c

Simplify:

1/2 = -1.5 + c

Add 1.5 to both sides

c = 2

Therefore, the equation of the line would be:

y = -1/2x + 2

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
