The line with intercepts a and b is
x/a + y/b = 1
So your line has the equation
x/4 + y/-3 = 1
Multiply that by -3 and you have
-3/4 x + y = -3
y = 3/4 x - 3
so the slope is 3/4
x/a + y/b = 1
So your line has the equation
x/4 + y/-3 = 1
Multiply that by -3 and you have
-3/4 x + y = -3
y = 3/4 x - 3
so the slope is 3/4
