Which of the lines graphed has a slope of -1/2 and a y-intercept of 3
MAXImum [283]

Answer:

The correct option is C).

Figure show the line with slope of -1/2 and a y-intercept of 3

Step-by-step explanation:

The equation of line is given by y=mx+c.

Where m is slope and c is y-intercept.

Given that line has slope

m=\frac{-1}{2} and c=3

Thus equation of line will be

y=mx+c.

y=\frac{-1}{2}x+3

To plot the line we need at least two points

Take x=0

y=\frac{-1}{2}x+3

y=\frac{-1}{2}0+3

y=3

The required point is A(0,4)

Take x=2

y=\frac{-1}{2}2+3

y=2

The required point is B(2,2)

Using this points to graph the given equation of line

Figure show the line with a slope of -1/2 and a y-intercept of 3

The correct option is C).
