Use substitution to solve each system of equations.
x – 5y = –3
–7x + 8y = –33

a(2, 7)

b(–5, 1)

c(7, 2)

d(1, –5)

For this case we have a system of sos equations with two unknowns:

We clear "x" from the first equation:

We substitute in the second equation:

We find the value of "x":

(7,2)

Option C

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
