Final answer:
The equation of the line with a y-intercept of 3 and a slope of 2/5 in slope-intercept form (y = mx + b) is y = (2/5)x + 3.
Step-by-step explanation:
The equation of the line with a y-intercept of 3 and a slope of 2/5 in slope-intercept form (y = mx + b) is y = (2/5)x + 3.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.
Since the y-intercept is 3 and the slope is 2/5, we can substitute these values into the slope-intercept form to get y = (2/5)x + 3.
