Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.

Or means not both
if people study both then the number of people studying either french or spanish is 7 less than the total number of peple studig french and spanish because thoe 7 are common to both groups

23-7=16 people studing either
proabblity=desiredoutcmes/totalpossibe
desired=16
total=30
so 16/30=8/15 is the probablity
