First, we will calculate the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
m = (2 - (-2)) / (-7 - 3)
m = 4 / -10
m = -2/5
Now that we have the slope, we can use it to find the y-intercept (b) by substituting one of the points into the slope-intercept form of a linear function (y = mx + b). Let's use the point (3, -2):
-2 = (-2/5)(3) + b
-2 = -6/5 + b
b = -2 + 6/5
b = -2 + 1.2
b = -0.8
Now we have the slope (m) and y-intercept (b), so we can write the equation of the linear function:
y = -2/5x - 0.8
