Question

How do you convert y + 13=4(x+2) into slope intercept form?

Answer 1

Simplify the equation first...use the distributive property on the right side.

Answer 2

y+13 =4x+8

Slope intercept form is y=mx+b. You must get y by itself by moving 13 to the other side of the equation and simplifying.

Answer 3

okay so would do 4x-13?

Answer 4

not quite...you'd have y+13-13 = 4x +8-13
when you simplify, you'd get y=4x-5

Answer 5

You lost the +8...don't throw it away, just combine it with the -13

Answer 6

why did the 13 turn negative?

Answer 7

4 + 6 = 10
6 = 10 - 4

see how 4 turned negative?

Answer 8

You had to get y by itself. y+13 = 4x+8
y+13-13 = 4x+8-13
y+0 = 4x-5
y=4x-5 does that make sense

Answer 9

one invisible step that we don't normally show in simple arithmetic is this part

4 - 4 + 6 = 10 - 4

Answer 10

to move any variable or value from one side to another, its property changes into opposite
from + to -
from - to +
from x to ÷
from ÷ to x

Answer 11

yes, it makes a lot more sense now, thank you dss and nincompoop i did not know that helps a lot! thank you to you both. :)

Answer 12

You're welcome. Good questions
