Question 12 Multiple Choice Worth 1 points)
serg [7]

Answer:

y - 3x = -10

Step-by-step explanation:

Complete question

<em>Choose the equation below that represents the line passing through the point (2, -4) with a slope of 3</em>

The standard equation of a line in point-slope form is y-y0 = m(x-x0)

Given

x0 = 2

y0 = -4

alope m  = 3

Substitute

y - (-4) = 3(x - 2)

y + 4 = 3(x - 2)

y + 4 = 3x - 6

y - 3x = -6 - 4

y - 3x = -10

Hence the required equation is y - 3x = -10

Apply minus/plus rule:

2*10xx-2*1*x

Simplify 2*10xx-2*1*x:

2*10xx= 20x^2

2*1*x= 2x

20x^2-2x
