Answer:
-5
4
Step-by-step explanation:
x + x² = 20
x² + x - 20 = 0
Factor
(x + 5)(x - 4) = 0
x = {-5, 4}
-5 + 25 = 20
4 + 16 = 20
The slope of line passing through given points is: 2
Step-by-step explanation:
Let us define slope first
Slope is the steepness of a line
Slope is denoted by m
The formula for slope is:
Given points are:
(2,1) (-1,-5) and (3,3)
We will takes any two points to find the slope of the line passing through the points
So we take
(2,1) = (x1,y1)
(-1,-5) = (x2,y2)
Putting the values in the formula
The slope of line passing through given points is: 2
