Answer:

#4

Step-by-step explanation:

1) The y intercept is 0.

2) Convert to slope-intercept form:

2x + 3y = 12

3y = -2x + 12

y = -2/3 x + 4

So the y-intercept is 4.

3) Write in point-slope form:

y + 4 = 2 (x - 1)

Now convert to slope-intercept form:

y + 4 = 2x - 2

y = 2x - 6

So the y-intercept is -6.

4) The y-intercept is 5.

So of the four lines, #4 has the largest y-intercept.

The line with an  x-intercept of -1 and a  y-intercept of 1 is C. x - y = -1

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept

Given the line x - y = -1, the x intercept is at y = 0, hence:

x - 0 = -1

x = -1

The y intercept is at x = 0, hence:

0 - y = -1

y = 1

The line with an  x-intercept of -1 and a  y-intercept of 1 is C. x - y = -1
