Select the descriptions that are true of the equation y - 6= - 3(x+2). select all that apply. slope = 1 slope = -3 (2, -2) is a point on the line. (-2, 6) is a point on the line. select the equation written in point-slope form. 2x - y=4 y=2x-4 y+2=2(x - 1) y - x=4

The point-slope form:

We have

Therefore

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

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

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
