Answer:
The equation of the line that passes through the point (2, -1) and has a slope of -3 will be:
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given
substituting m = -3 and the point (2, -1) in the slope-intercept form of the line equation
y = mx+b
-1 = -3(2)+b
-1 = -6 + b
b = -1 + 6
b = 5
Thus, the y-intercept form of the line equation is b = 5
now substituting b = 5 and m = -3 in the slope-intercept form of the line equation
y = mx+b
y = -3x + 5
Thus, the equation of the line that passes through the point (2, -1) and has a slope of -3 will be:

<span>Mindy and troy combined 9 pieces of the wedding cake.
Mindy ate = 3 pieces of cake
Troy = had ¼ of the total cake.
Now, let’s find an equation that will give us the total number of pieces of the
cake
=> Let X = Mindy
=> let Y = Troy
=> Let c = total number of cake
=> X + Y = 9, where x = 9 and y = ¼
Let’s find the number of pieces of cake that Troy’s have:
=> Y = 9 – x
=> Y = 9 – 3 = 6
=> Y = 6
Now, let’s find the number of Cake
=> 6 = c/4
=> c = 4 x 6
=> c = 24
Thus, there are 24 cakes in all.
