Answer:
x=30
Step-by-step explanation:
The slope between the two points (3,-2) and (4,7) is 9.
The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.
To find slope given two(x1, y1) and(x2, y2) points, we use the formula
Given coordinates are:(3,-2) and (4,7)
x1= 3, x2= 4 , y1= -2 and y2= 7
Using Formula,
= 9 /1
= 9
So, the slope between two points is 9.
