which equation describes the line passing through the points (3,0) and (0,4)

Answer 1

The line will have an equation of the form y=Ax+B where we have to identify the constants A,B. Since we want the given points to belong on the line we will have that 0=3A+B and 4=A0+B. So B=4 and A=-4/3. Hence, the line is given by the expression y=(-4/3)x+4.
