Write the equation of the line in fully simplified slope-intercept form.

(-3,7), (-6,8)

1 answer

To find the slope of the line passing through the points (-3,7) and (-6,8), we use the formula:

slope (m) = (y2 - y1) / (x2 - x1)

Plugging in the coordinates, we have:

slope (m) = (8 - 7) / (-6 - (-3))
slope (m) = 1 / -3

Next, we can use the slope-intercept form of a linear equation, which is:

y = mx + b

where m is the slope and b is the y-intercept.

Let's substitute the slope (m) into the equation:

y = (-1/3)x + b

Now, to find b (the y-intercept), we can substitute the coordinates of one of the points into the equation. Let's use (-3,7):

7 = (-1/3)(-3) + b
7 = 1 + b
b = 7 - 1
b = 6

Finally, we can write the equation of the line in fully simplified slope-intercept form:

y = (-1/3)x + 6
