y + 4 = (x + 9)
y + 4 = Image with alt text: three-fifths ( x + 9)
y + 4 = (x + 9)
y + 4 = Image with alt text: five-thirds ( x + 9)
y - 3 = (x + 6)
y - 3 = Image with alt text: three-fifths ( x + 6)
y + 3 = (x – 6)
The equation that represents the line that passes through the points (6, –3) and (–4, –9) is:
y + 4 = (x + 9)
Five-thirds or three-fifths
Apologies for the confusion. The correct equation that represents the line passing through the points (6, –3) and (–4, –9) is:
y + 3 = (x - 6)
To find the equation of the line that passes through the points (6, –3) and (–4, –9), we can use the point-slope form of a linear equation, which is given by:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line.
First, let's calculate the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
Using the given points (6, –3) and (–4, –9):
m = (-9 - (-3)) / (-4 - 6)
= (-9 + 3) / (-4 - 6)
= -6 / -10
= 3/5
So, the slope of the line is 3/5.
Now, we can choose one of the given points (let's choose the point (6, –3)) and substitute its coordinates along with the calculated slope into the point-slope form equation:
y - (-3) = (3/5)(x - 6)
y + 3 = (3/5)(x - 6)
Hence, the correct equation representing the line that passes through the points (6, –3) and (–4, –9) is:
y + 3 = (3/5)(x - 6)
