Find the slope and y-intercept of the following equation $3 y - 5 = 2 (x - 2)$
Slope= ?
y-Intercept=?
Q)Find the slope and y-intercept of the following equation $15 x + 3 y = 2.4$
Slope= ?
y-Intercept=?
Use algebra to solve the following systems of equations
A) $12 y = 5 x + 16$
$6 x + 10 y - 54 = 0$
B) $\frac{9 x}{5} + \frac{5 y}{4} = \frac{47}{10}$
$\frac{2 x}{9} + \frac{3 y}{8} = \frac{5}{36}$
C) $0.2 a + 0.3 b = 0$
$0.7 a + 0.2 b = 259$
1.General equation for slope is $y = m x + b$ . Where m is the slope and b is the y-intercept.
$3 y - 5 = 2 (x - 2)$
$3 y - 5 = 2 x - 4$ Simplifying,
$3 y = 2 x + 1$ .
$y = \frac{2}{3} \cdot + \frac{1}{3}$ .
Comparing the above equation with the generalised equation, we get, 2/3 as slope and 1 as the y-intercept.
$2.15 x + 3 y = 2.4$
$3 y = - 1.5 \cdot x + 2.4$
$y = - 0.5 \cdot x + 0.8$
Comparing the above equation with the generalised equation we get slope as -0.5 and y-intercept as 0.8
