Question

Select the descriptions that are true of the equation y - 6= - 3(x+2). Select all that apply.

Answer 1

The point-slope form:

$y-y_1=m(x-x_1)$

We have

$y-6=-3(x+2)\to y-6=-3(x-(-2))$

Therefore

slope = -3 and the point (-2, 6)

------------

y + 2 = 2(x - 1)

2x - y = 4    it's standard form Ax + By = C

y = 2x - 4     it's slope-intercept form y = mx + b

y - x = 4 → x - y = -4  t's standard form Ax + By = C
