Question

Which equation represents a line that has a slope of Negative one-half and passes through point (4, –5)?

1)y = negative one-half x + three-halves
2)y = negative one-half x + StartFraction 13 Over 2 EndFraction
3) y = negative one-half x minus 7
4) y = negative one-half x minus 3

Answer 1

ITS C

Explanation:

Answer 2

4) y = -1/2x - 3

Explanation:

Slope-Intercept Form: y = mx + b

Step 1: Write out known variables

m = -1/2

y = -1/2x + b

Step 2: Find b using known coordinates

-5 = -1/2(4) + b

-5 = -2 + b

b = -3

Step 3: Rewrite equation

y = -1/2x - 3
