Question 882803: Please help me solve this line graph.. I've tried to figure it out myself, no use.
"Which of the following equations describe the line shown below?"(3,2)and(-1,-4)
I've plotted it on this site hoping it would help me get a better idea of the question, https://www.mathway.com/
I was also wondering if you could explain what happens to x2 and y2, you see i arranged them in "slope formula" as my teachers call it (although i know there are many different names for it) and i understand where y1 and x1 go,but i don't understand what happens to x2 and y2. Also if you don't mind me asking where do you get and or find the m?

Question 883459: The formula for the slope of a line is given by m=y2-y1/x2-x1
Identify the true statement about the slope formula:
1)The subscripts 1 and 2 refer to the two intercepts of the linear equation
2)x^2 and y^2 should always be larger in value than x^1 and y^1 since they appear first in the formula
3)The x and y values represent the x and y coordinates of one point that is on the graph of the linear equation and one that is NOT on the graph of the linear equation
4)The x and y values represent the x and y intercepts of the two different linear equations
5)The x and y values represent the x and y coordinates of two points of the linear equation
