the slope, the y-intercept, and the x-intercept of the following linear
equations. Determine what type of line it represents: upwards, downwards,
horizontal or vertical.
(a) 4x
+ 2y = 25
(b) 2x
– y = 10
(c) 2y
= 100
(d) x =
12
3. Solve the following system
of equations using the graphical method. Also find the solution using the
method of elimination or the substitution method.
3x + 2y = 7
8x + 4y = 16
4. Find the feasible region
for the following system of inequalities.
x
+ y > 2
8x + 6y ≤ 48
Notes:
– Homework 1 is due by midnight Sunday, September 11th.
– Each student must solve
Homework 1 problems individually by himself/herself or within the team he/she is a member of. Please do not ask for
help from anyone else to answer any questions in this homework. Also, do not
