Bot GPT 3.5 To find the slope of the line passing through the points (1,-19) and (-2,-7), we can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates, we get:
m = (-7 - (-19)) / (-2 - 1)
= (-7 + 19) / (-2 - 1)
= 12 / (-3)
= -4
Now that we have the slope (m = -4), we can write the equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
Using the point (1,-19) to find the value of b, we can plug in the values into the equation:
-19 = -4(1) + b
-19 = -4 + b
b = -19 + 4
b = -15
Therefore, the equation in slope-intercept form is:
y = -4x - 15
