To find the equation of the line in slope-intercept form (y = mx + b), we first need to find the slope (m) and the y-intercept (b).
The slope (m) can be found using the formula:
m = (difference in y-coordinates) / (difference in x-coordinates)
m = (1 - (-3)) / (3 - 1)
m = 4 / 2
m = 2
Next, we can substitute one of the given points into the equation y = mx + b to find the y-intercept (b). Let's use the point (1,-3):
-3 = 2(1) + b
-3 = 2 + b
b = -3 - 2
b = -5
Therefore, the equation of the line in slope-intercept form is:
y = 2x - 5
The correct answer is: y = 2x - 5
What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3, 1)?
