Write the equation of the line in slope intercept form that passes through the points (-3,5) and (2,-5)
:
Assign the given coordinates as follows:
x1 = -3; y1 = 5
x2 = 2; y2 = -5
:
Use the slope formula to find the slope (m): m =
:
Using our values:
m =
which is:
m = =
m = -2
:
Use the point/slope formula to find the equation: y - y1 = m(x - x1)
:
y - 5 = -2(x - (-3))
y - 5 = -2(x + 3)
y - 5 = -2x - 6
y = -2x - 6 + 5
y = -2x - 1; is the slope intercept equation
:
:
You can substitute the given values for x in the above equation
Confirm that you get the given values for y
:
How about these steps, did they make sense to you?
