| Abstract: | - Graphing the following linear equations:
a) 2y + 6x = 6 b) 12x + 4y = -4 c) y = 3 d) y = 2x + 1e) y = -½ x – 2 Identify the slope and y-intercept of the lines above.- Describe a relationship between the graphs of part d and part e.
- What do you notice about the slopes? a) x + y = 7 (2,5) (-2,-5) (-3,10)
b) 2x – y = 8 (4,0) (1,-7) (-2,-12)If a line passes through the given point (x1, y1) and has a slope m, the point-slope form of the equation of the line is y – y1 = m(x – x1).- Ex) Write an equation of a line that has a slope of –2 and passes through the point (4,2).
- Ex)Write an equation of the line with a slope of -½ and passes through the point (-4,-2)
Ex) Write an equation of ... |
