Answer:

The critical value is T = 3.143.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 7 - 1 = 6

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.98}{2} = 0.99. So we have T = 3.143.

The critical value is T = 3.143.

2x-3y=2 for graphing systems of linear equations
Galina-37 [17]

Answer:

-2/3 is the y intercept

Step-by-step explanation:

So to find the y-intercept you must first put this in Slope-intercept form, I believe the form it is in right now is called standard form.

To get it into slope intercept form, we have to isolate y:

subtract 2x from both sides:

-3y = -2x + 2

Divide both sides by -3:

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

Now that we have slope-intercept form, we can find the y-intercept. We know slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case the y-intercept is -2/3.

Hope this helps!
