Find the slope and y intercept for(-4,-,0)

The slope is -4 

This is because I did 0- ( -3 ) which gave me -3 and then I did 8- ( -4 ) which gave me 12 and then divided the 2 numbers and got -4. :)

The y-intercept is 29..
 
 This is because I took 2 points for the parenthesis above... ( -4,3,8,0 ) and did -3=-4(8) +b then I did the math and got the equation -3 = -32+b and being that this is negative I added instead of subtracting... this then canceled out the -32 and that left me with -3 plus 32 and gave me my answer which is 29 ... I hoped that this helped

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
