To find the equation of the linear function, we first need to calculate the slope (m) using the coordinates of the two points.
m = (y2 - y1) / (x2 - x1)
m = (4 - (-1)) / (2 - (-3))
m = 5 / 5
m = 1
Next, we can choose one of the points to plug into the equation y = mx + b to solve for the y-intercept (b). Let's use the point (2, 4):
4 = 1(2) + b
4 = 2 + b
b = 2
Therefore, the equation of the linear function is y = x + 2.
