Question 729299: Write a slope-intercept equation for a line with the given characteristics.
m = - 3/5, passes through (-4,-1) y = mx + b
I thought it would be y = -3/5(-4) + -1
y = 12/5x + -1
The answer in the book says it's y = -3/5x - 17/5
I don't understand what happened with (-4,-1) or how the y-intercept became 17/5.
The book example only shows a simple m = -4, y-intercept (0,-7) Which I know is Y = -4x - 7.
I didn't take Algebra in high school. (I've been out for a lot of years) College Algebra is required for my degree, and it is draining me. I spend hours watching teachers on you tube.
Thank you for any steps and help you can give me.

Question 729547: Hi there! I'm wondering what the best method would be to solve a system of three linear inequalities with only two variables each?
Example:
3x+5y �(or equal to) 180
5x+2y �(or equal to) 90
8x+3y �(or equal to) 240
My first instinct was to solve using the elimination method, but I don't know how to apply it to 3 equations.
I'm on my tablet, so I apologize that I can't use the less-than-or-equal-to symbols.
Any help is immensely appreciated!

Question 730739: x-3y+3=0
I am supposed to put this into slope intercept form and then find three coordinates for (x,y). I THINK I am doing the math correctly, but I so far I have come up with THREE different solutions for (x,y). Also, when I go to graph this on my online homework, the answers are wrong. My tutor will not be here until five, and I really want to learn how to do this to the best of my ability so that my tutor and I can spend more time on the other things I am struggling with. Can you include the three correct points on a picture of a graph so I can see what it looks like? Any help is very much appreciated. Thank You.

Question 731084: It is a multiple choice question: Which one of the following equations represents a line that is perpendicular to the line with equation
5x - 3y + 4 = 0
The options are:
1. 5x � 3y + 10 = 0
2. 10 + 5y= 3x
3. 5x = � 3y � 10
4. 3x + 5y + 10 = 0
5. 5x � 3y + 10 = 0
I think the slope of the given line is 5/3, so the slope of the perpendicular line will be -3/5, but how do I get to the perpendicular line's equation then?
I think the answer is 4, but not sure at all!
