I need help on this and D is y+4=2(x+1)
kodGreya [7K]

Answer:

A; y- 4 = -2(x + 1)

Step-by-step explanation:

Here, we want to find the equation of the given line

The general form

is ;

y = mx + c

c is the y-intercept which is 2

So we have

y = mx + 2

The x-intercept where y = 0 is 1

Thus;

0 = m(1) + 2

0 = m + 2

m = -2

So the equation of the line is

y = -2x + 2

We can rewrite this in the point-slope form as:

y - 4 = -2(x + 1)
