(2x-1)(4x+3)=0

Solve:

2x-1=0

Write the equation of the line that passes through the point (-2, 4) and has a slope of -1. Show work please
vovangra [49]

Answer:

y = -x + 2

Step-by-step explanation:

If you know the slope and a point on the line, then you can find the equation with an equation:

(y - y1) = m (x - x1)

We have our slope, -1; we have a x1, -2, and a y1, 4, so we're all set to find the equation. Plug in the numbers:

y - 4 = -1 ( x + 2 )

y - 4 = -x - 2

y = -x + 2

Our equation is y = -x + 2
