Find an equation for the line that passes through the points (-3, -3) and (5, -5).

3 answers

First, calculate the slope using the formula:

m = (y2 - y1) / (x2 - x1)
m = (-5 - (-3)) / (5 - (-3))
m = (-5 + 3) / (5 + 3)
m = -2 / 8
m = -1/4

Next, choose one of the points to use in the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Using the point (-3, -3):

y - (-3) = (-1/4)(x - (-3))
y + 3 = (-1/4)(x + 3)
y + 3 = (-1/4)x - 3/4

Now, simplify the equation:

y = (-1/4)x - 3/4 - 3
y = (-1/4)x - 3/4 - 12/4
y = (-1/4)x - 15/4

Therefore, the equation of the line passing through the points (-3, -3) and (5, -5) is y = (-1/4)x - 15/4.

Apologies for the error in my previous response. Let's find the correct equation.

First, calculate the slope using the formula:

m = (y2 - y1) / (x2 - x1)
m = (-5 - (-3)) / (5 - (-3))
m = (-5 + 3) / (5 + 3)
m = -2 / 8
m = -1/4

Next, use the point-slope form of the equation of a line with one of the points, say (-3, -3):

y - y1 = m(x - x1)
y - (-3) = (-1/4)(x - (-3))
y + 3 = (-1/4)(x + 3)
y + 3 = (-1/4)x - 3/4

Now, simplify the equation:

y = (-1/4)x - 3/4 - 3
y = (-1/4)x - 3/4 - 12/4
y = (-1/4)x - 15/4

Therefore, the correct equation of the line passing through the points (-3, -3) and (5, -5) is:
y = (-1/4)x - 15/4.
