Answer:
y=4x-16
Explanation:
The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.
Given points (-3,-3) and (-1,5)
We are to find the equation of the line parallel to the given line with an x-intercept of 4.
First, we determine the value of the gradient of the line.
Gradient,
Two lines are parallel if their gradients 
are equal.
The gradient of the line parallel to the given line 
Since the x-intercept of the new line is 4, a point on the new line, 
Substituting into the equation of a line: , 
we have:
Therefore, the equation of the line is: y=4x-16
Answer:
tornadoes are formed by mixing cold and hot air together.
Explanation:
Because hot air rises, when hot air from the west, clashes with cold from the east (or visa versa) the hot air rises above the cold air and causes drag on the inside of the cold air, which makes the inside of the cold air travel at a slower rate than the outside of the cold air, which in turn makes the cold air turn in on itself.
because the cold air turns in on itself, any warmer air underneath rises above the swirl of cold air forcing it to sink to earths level. "friction" or "resistance" between the swirl of cold air and the earth's surface creates more energy that is absorbed by the cold air molecules in the swirl of air, allowing the particles to move quicker and quicker in the direction they are travelling in (a bend or circle), creating a tornado.
Answer: Disarmament and settling of border disputes contributed to the League of Nations' goal of preventing future warfare.
