This is going on in Mrs. Preisner's Algebra, Basic Algebra I & II and Informal Geometry classes.
1.) What is the slope and y-intercept of the following equation? 2x + 3y = 7
A.) M = 2/3 B = 7/3
B.) M = 7/3 B = 2/3
C.) M = -2/3 B = 7/3
D.) M = 7/3 B = -2/3
2.) Find A given the other two sides of a right triangle.
A.) 20.78
B.) 26.83
C.) 12
D.) 23.65
3.) Given these two ordered pairs, (2, 3) ( 3, -4), Find the following:
A.) Slope
a.) 1/7
b.) -7
c.) -1/7
d.) 7
B.) Point Slope Form
a.) y - 3 = -1/7(x - 2)
b.) y - 2 = -7(x - 3)
c.) y - 2 = -1/7(x - 3)
d.) y - 3 = -7(x - 2)
C.) Slope-Intercept Form
a.) y = -7x + 17
b.) y = 17x - 7
c.) y = -1/7x + 17
d.) y = 17x - 1/7
D.) Standard Form
a.) x - 7y = 17
b.) x + 7y = 17
c.) 7x + y + 17
d.) -7x + y = 17
