To find the equation of the first line, let's first determine the slope using the given points (2,-13) and (-2,-1):
m = (y2 - y1) / (x2 - x1)
m = (-1 - (-13)) / (-2 - 2)
m = 12 / -4
m = -3
Next, let's use one of the points (2, -13) to find the y-intercept (b):
y = mx + b
-13 = -3(2) + b
-13 = -6 + b
-7 = b
Therefore, the equation of the first line is:
y = -3x - 7
To find the equation of the second line, let's first determine the slope using the given points (5,-22) and (-3,2):
m = (y2 - y1) / (x2 - x1)
m = (2 - (-22)) / (-3 - 5)
m = 24 / -8
m = -3
Next, let's use one of the points (5, -22) to find the y-intercept (b):
y = mx + b
-22 = -3(5) + b
-22 = -15 + b
-7 = b
Therefore, the equation of the second line is:
y = -3x - 7
Both equations are the same, indicating that the two lines are the same line and have many solutions.
Susie determined that the system of equations below has many solutions the first line goes through the points (2,-13) and (-2,-1)
the second lines goes through the points (5,-22) and (-3,2)
