A1. The line given by the equation $4 x+7 y-3=0$,
(A) is increasing
(B) is decreasing
(C) intersects the x-axis at $x=1$
(D) intersects the y-axis at $y=-1$
(E) is parallel to the y-axis
A1. From the explicit form of the line equation $y=-\frac{4}{7} x+\frac{3}{7}$, we read the slope coefficient $k=-\frac{4}{7}$. The function is decreasing because the slope coefficient is negative.
