Question

show me how to graph the line for (4.3)(-4-5) and the given pair of points to find slope

Answer 1

slope = y2 - y1/ x2 - x1
m = -5 - 3/ -4 -4
m = -8/0

Answer 2

I assume the 2 points are (4,3) and (-4,-5)


To find the equation between 2 points, first find the slope (called m)
the slope is the distance in y divided by the distance in x
\[m=\frac{y_2-y_1}{x_2-x_1}\]
Here we get
\[m=\frac{-5 - 3}{-4-4}= \frac{-8}{-8}= 1\]
Now use m in the formula
\[y-y_1= m(x-x_1)\]
where x1,y1 is one of the points (either one will do). Let's use (4,3):
y-3= 1*(x-4)
we get
y= x-4+3 or
y= x-1
