Because one is negative and one is positive
Answer:
y-intercept = (0,
).
Step-by-step explanation:
Given the linear equation in standard form, 12x + 13y = 8:
We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.
12x + 13y = 8
Subtract 12x from both sides:
12x + 13y - 12x = - 12x + 8
13y = - 12x + 8
Next, divide both sides of the equation by 13 to solve for y:

or 
Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is the point where the graph of the linear equation crosses the y-axis).
Let x = 0:


Therefore, the value of y when x = 0 is
. This is the y-intercept, and its coordinate is (0,
).
For the limit to exist, the limits from either side must also exist and be identical. We have


Since the limits do not match, the overall limit does not exist.
Use 340 as an estimate for 339.
339+214 is approximately 340+200 = 540
