A line has a slope of -
and a y-intercept (vertical intercept) of 9.

The first one is correct you take the slope and multiple it by x and then add or subtract your y intercept depending on whether it is positive or negative. In this case it's positive so it would by -3/7x+9

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
