You can put this solution on YOUR website!
YOUR QUESTION IS NOT CLEAR AS THE REFERENCE BOOKS ARE NOT AVAILABLE WITH US.BUT IF YOU ARE LOOKING FOR STRAIGHT LINES,SLOPE ETC...YOU MAY READ THE FOLLOWING EXAMPLES
This question is from textbook beginning algebra
3x+5y=1
4x-5y=2
2x+3y+5=0
Then instructions says to find the slope of the line.
I tried working these problems but I am not fully understanding what to do first. Can you give me a break down step by step how to do these problems. thanks so much for your help.

3x+5y=1
FIRST PUT THE EQN. IN STD. FORM
Y = MX + C
THAT IS KEEP ONLY Y..[NOTE ONLY +1*Y IT SHOULD BE] ON LHS AND TRANSFER X AND CONSTANT TERMS TO RHS.
THEN M THE COEFFFICIENT OF X IS THE SLOPE AND CONSTANT TERM IS THE Y INTERCEPT OR CALLED THE INTERCEPT IN SHORT
HERE WE GET
5Y=-3X+1
Y=-3X/5 +1/5
HENCE M= SLOPE = -3/5
AND INTERCEPT = 1/5
4x-5y=2 ....SIMILARLY
M=4/5......INTERCEPT = -2/5
2x+3y+5=0
M= -2/3..INTERCEPT = -5/3
Then instructions says to find the slope of the line.
