Medal will be given.

Write the equation in slope-intercept form of the line that has a slope of 5 and y-intercept of -3

Answer 1

how do you define the slope intercept form?

Answer 2

That I have no idea.
I think its something like y=mx+b

Answer 3

thats actually correct

Answer 4

now, m is a placeholder for the slope; and b is a placeholder for the value of the y intercept

just plug and play

Answer 5

y=5x-3?

Answer 6

excellent

Answer 7

Now I have another problem I would like help on.

Answer 8

*Write the equation in slope-intercept form of the line that has a slope of -3 and contains the point (4,-5)

Answer 9

use y-y1=m(x-x1) form then subtract the value of y1 from both sides

Answer 10

I can not get the answer for that.

Answer 11

All I have so far is -3x+12

Answer 12

subtract 5 from the 12 so you would get -3x+7

Answer 13

But my y1 is a -5

Answer 14

yeah the form is y-(-5) which equals to y+5, so u subtract five from both side to leave the y by itself

Answer 15

So the answer is y=-3x+7?

Answer 16

Yes
