Please help I really need it I am in a timed test I will choose brainliest!

Write the standard form of the equation of a line with a slope of -4 passing through the point (1, -4).

Select one:
a. -4x - y = 0
b. -x - 4y - 15 = 0
c. x + 4y + 15 = 0
d. 4x + y = 0

Respuesta :

I think the answer is a.

Answer:

Step 1: We must determine the equation of the line in slope-intercept form* by solving for b.

[tex]-4 = -4(1) + b\\\\-4 = -4 + b\\\\0 = b[/tex]

Step 2: Now we write the equation in slope-intercept form.

[tex]y = -4x[/tex]

Step 3: We can now change the above equation to standard form by moving variables to one side.

[tex]y = -4x\\\\4x + y = 0[/tex]

Our answer is D. 4x + y = 0.

*Slope-intercept form: y = mx + b.
