Make a graph and start at the origin (0,0) count down 5 units and across to the right 4 units. Put a dot here. For every 1 unit the line moves to the right, it moves down 3.
Each downloaded song costs $1.19. ... Join now. 1 ... Write and solve an inequality to determine how many songs ... This means he can spend less than $10 or exactly $10;
Each time x increases by 2 (eg: from x = -3 to x = -1), the value of y increases by 7 (eg: y = 9.5 to y = 16.5)
Change in y = 7
change in x = 2
Slope = (change in y)/(change in x) = 7/2 = 3.5
This all means that we have a linear equation
GH: chord
M: point of tangency
MJ: diameter
