The equation of a line can be written in slope-intercept form like this:
y = mx + b
Where m is the slope of the line and b is the Y-intercept. The slope of a line is given by the following formula:
Where (x1, y1) and (x2, y2) are two points where the line passes through. In this case, by taking the points (-9, -9) and (-6, 0) we get:
Then we can rewrite the equation of the line like this:
y = 3x + b
By replacing the coordinates of the points (-6, 0) we get:
0 = 3(-6) + b
0 = -18 + b
18 = -18 + 18 + b
18 = b
b = 18
By replacing 18 for b and 3 for m we get:
y = 3x + 18
Hey there!
The formula is: y2 - y1 / x2 - x1
y2 = 11
y1 = 5
x2 = 4
x1 = 1
Equation: 11 - 5 / 4 - 1
11 / 5 = 6
6 / 4 - 1
4 - 1 = 3
6/3 = 2
Answer: 2 ☑️
Good luck on your assignment and enjoy your day!
