Answer:
y = -3/7x +3
Explanation:
The two intercepts are given, so the intercept form of the equation for a line can be a place to start:
x/(x-intercept) +y/(y-intercept) = 1
x/7 +y/3 = 1 . . . . an equation for the line
To put this in slope-intercept form, we need to isolate the y-term, then make its coefficient be 1.
y/3 = -x/7 +1 . . . . . subtract the x-term
y = -3/7x +3 . . . . . multiply by 3. slope-intercept form
