Answer:
y = -3, slope = 0
Step-by-step explanation:
1) First, find the slope of the line. Substitute the x and y values of the given points into the slope formula, 
, and solve:
Thus, the slope is 0.
2) If a line has a slope of 0, that means it is horizontal. All horizontal lines are represented by the equation y = a number. That number is determined by the y-value of all the points the line intersects. Thus, find the y-value of the given points and put it into the equation. Looking at the given points, that number would be -3, so y = -3 is the equation.
Please, post just one question at a time. I am arbitrarily focusing on #24 this time thru.

2x - 4y = 3 can easily be solved for y: 2x-3=4y, or y = ---------

The slope of this line is m = 2/4, or m = 1/2.
We need the equation of a new line parallel to this one. Use the slope-intercept form of the equation of a straight line: y = mx + b.
Let m = 1/2 and arbitrarily choose y-intercept b = 0. Then we have
y = (1/2)x + 0, or y = (1/2)x.
Want the equation of a line perpendicular to <span>2x - 4y = 3?
We already know that the slope of this given line is 1/2. The slope of a line perpendicular to this given line is the neg. reciprocal of 1/2, or m = -2.
Again, use the slope-intercept formula y = mx + b:
y = -2x + 0 (my choice of b = 0 is arbitrary; could have chosen some other value for b)</span>
Fewer because when there is boxes with larger quantities of cereal, they will need less boxes because of the box to cereal ratio. I hope this helps!
The South became convinced that Lincoln was an abolitionist even though did not state that he wanted to ban slavery.
