Which equation is a point slope form equation for line AB? Oy+2 = -2(3-5)
А
Oy+6= -2(x - 1)
Oy+1=-2 (3-6)
Oy+5 = -2(3-2)

Step-by-step explanation:

Given; The graph above

Required: Equation of line AB (in point slope form)

First, we need to determine the slope of the graph;

From the graph; we can observe that when y = 6, x = 1 and when y = 2, x = 3

Such that

The slope of a line is define as thus;

Considering only point ; The slope is define as thus

Substitute and

Multiply both sides by x - 1

Rearrange

Hence, the equation of the line is a point slope form is

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
