Which equation represents a line that has a slope of -1/2 and passes through point (4, -5)?

O y= -1/2x + 3/2
O y= -1/2x + 13/2
O y = - 1/2x - 7
O y= 1/2x -3

Answer:

D

Step-by-step explanation:

Since we are given the slope, find the y-intercept using the formula for slope intercept form [ y = mx + b ].

y = -1/2x + b

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

-5 = -2 + b

-3 = b

Put everything we know into final form.

y = -1/2x - 3

Best of Luck!

Answer:

D. [tex]y = -1/2x - 3[/tex]

Step-by-step explanation:

To solve this we must use the Point-Slope formula:

[tex]y-y1=m(x-x1)[/tex]

Substitute:

[tex]y+5=-1/2(x-4)[/tex]

Distribute:

[tex]y+5= -1/2x + 2[/tex]

Subtract 5 from both sides:

[tex]y = -1/2x - 3[/tex]

Hope this helped!
