Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
You had assignment that is over due but you need extra time what is a good excuse to tell your teacher why you need extra time work on the assignment
80 km
You do 240/60 which is 4 and then times that by 20. By dividing 240 by 60 you are finding how far it goes per minute and then you times that by how many minutes(20) which is 80 km
