Question

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

(WORTH 100 POINTS AND WILL GIVE BRIANLIEST)

Answer 1

B

Explanation:

I’m not sure but I put in c and got it wrong and that is the only other one that appears to be going on a negative slope

Answer 2

The correct option is C).

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

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=
`(-1)/(2)` and c=3

Thus equation of line will be

y=mx+c.

y=
`(-1)/(2)x+3`

To plot the line we need at least two points

Take x=0

y=
`(-1)/(2)x+3`

y=
`(-1)/(2)0+3`

y=3

The required point is A(0,4)

Take x=2

y=
`(-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).
