You're talking about one of the online questions on online homeschooling correct?
The cell labeled "a" is a joint frequency of 48
The cell labeled "b" is a marginal frequency of 93
Using the two coordinates you can find the equation
------------------------------------
Find slope first
Slope

0 - 3 = -3
-------
-4 - 0 = -4
--------------------------------------------------
Simplify -3/-4
3/4
-----------------------------------------------------------
Your slope is 3/4 and the Y-intercept as mentioned in the question is "3"
----------------------------------------------------------------------
So your equation is y = 3/4x + 3
Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
In our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
