A line passes through the points (2,3) and (-4,-5). Find: (a) the slope of the line (b)The equation of the line (c) the x-intercept (d) The equation of the perpendicular line passing through (1,-2) (please explain)
i sent u a message on this it might help u
hold on....let me help you
thank you boldjon but i need an explanation on how you got those answers and thank you Daniel56k
ok so let's start with a
luckily for u i was doing this with someone else so i'll just show u what i showed him
You want to find the equation for a line that passes through the two points: (2,3) and (-4,-5). First of all, remember what the equation of a line is: y = mx+b Where: m is the slope, and b is the y-intercept First, let's find what m is, the slope of the line... The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
the most important this is the slope formula
