Slope-intercept question?

Question

How would I write these in slope in slope-int form?

3(2 - 2x) = 6y + 8

-6y - 3x = 7 - 9x

Also, are they perpendicular?

Answer 1

slope intercept form is y = mx + b

3(2-2x) = 6y + 8
6 - 6x = 6y + 8
-2 - 6x = 6y
y = -1/3 - x
Slope is -1

-6y - 3x = 7 - 9x
6x -7 = 6y
y = x - 7/6
Slope is 1

Yes, they are perpendicular.
Two lines are perpendicular if the slope of one (m) is equal to the negative reciprocal (-1/m) of the other

Answer 2

as a rule, slope intercept variety is y=mx+b. M being the slope of the line and B being the y-intercept of the line (the place the line crosses the y axis) ingredient slope variety is used whilst given a ingredient on the line. The equation is: y-y1=m(x-x1) to illustrate, permit's say you have a line and the slope is 4 and a ingredient on the line is (a million,2)... your equation could be y-2=4(x-a million) slope intercept variety: y=x-9 ingredient slope variety: y-9=a million(x-0)

Answer 3

solve for y
