For each of the equations below, solve for y in terms of x. ! a. 2x – 3y = 12

ira [324]

Answer:

$\large\boxed{y=\dfrac{2}{3}x-4}$

Step-by-step explanation:

$2x-3y=12\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\2x-2x-3y=12-2x\\\\-3y=12-2x\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3y}{-3}=\dfrac{12}{-3}+\dfrac{-2x}{-3}\\\\y=-4+\dfrac{2}{3}x$

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?

Elena L [17]

Answer:

y + 7 = $\frac{1}{2}$ (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = $\frac{1}{2}$ and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = $\frac{1}{2}$ (x - (- 6) ) , that is

y + 7 = $\frac{1}{2}$ (x + 6)
