To find the equation of the line passing through the points (3,3) and (8,8), we first calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
m = (8 - 3) / (8 - 3)
m = 5 / 5
m = 1
Now that we have the slope, we can write the equation of the line passing through the origin in slope-intercept form (y = mx).
y = 1x
Since the slope is 1, the equation simplifies to:
y = x
