Today we learned about:
Graphing Linear Equation - a linear equation in two variables is an equation whose graph in the co-ord plane is a straight line.
Here' is today's assignment.
Go to Exercise 6 in your book and do odd numbers from 1-9 and 10, 11, 12.
1. y = 2x + 2
3. y = 5x + 5
5. 3x - 2y = 6
7. x = 3
9. y = 1
10. Simplify: (2x^4y)²(3xy³) / 6xy^5
11. Solve for x: 3 - [2 - (x - 2)] = 2x
12. Solve for x: 3x + 1 / 2 + 3 = x

Heey, today Dr. Eviator went over Excercise 7: Ques 1-3, 5-7 with the class. Our assignment is to do whatever we were supposed to finish today and also Excercise 7: 11, 16, 17 and Excercise 8: 6, 7. Here they are:
Excercise 7: 11, 16, 17:
11) AB = 3, BC = 4, DE = 10
How long is DC?
Excercise 7: 11, 16, 17:
11) AB = 3, BC = 4, DE = 10
How long is DC?
16) Find the length and midpoint of segment PQ given P(3, 2) and Q(-1, 4).
17) The midpoint of AB is M(1/2, 6). Given A(3, 7), find the coordinates of B.
Excercise 8: 6, 7:
6) Select any point on a sheet of graph paper, and call it A. Move two units to the left to point B. From there move five units up to point C and three units right to point D.
a) Find the slope of AD.
b) Find the distance between A and D.
7) What is the slope of
a) the x-axis?
b) the y-axis?
annnnd the next scirbe for monday is . . . arvee.
