Question
For the equation given below, find the slope and the $y-$intercept$:3y = 7$
✓
Answer
Equation of any straight line in the form $y = mx + c,$ where slope $= m($co$-$efficient of $x)$ and $y-$intercept $= c($constant term$)$
$3y = 7$
$3y = 0 · x + 7$
$y =\frac{0}{7} x+\frac{7}{3}$
$y=0 \cdot x+\frac{7}{3}$
Therefore,
slope $=$ co$-$efficient of $x = 0$
$y-$intercept $=$ constant term $=\frac{7}{3}$.
