To derive the equation of the line in slope-intercept form, we need to first find the slope of the line using the two given points.
The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:
m = (y2 - y1) / (x2 - x1).
Given point one is (0,-3) and point two is (1,1), we can substitute the coordinates into the formula:
m = (1 - (-3)) / (1 - 0)
m = (1 + 3) / 1
m = 4.
Now that we found the slope, we can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
Since the line passes through point one (0, -3), we can substitute the x and y coordinates into the equation to solve for b:
-3 = 4(0) + b
-3 = 0 + b
b = -3.
Now that we found the y-intercept, we can write the equation of the line in slope-intercept form as:
y = 4x - 3.
