Question

Write an equation for each line in slope intercept form

Answer 1

Answer:

Blue = y = -2x - 5                           Red = y = -3x + 3

Step-by-step explanation:

Blue line

y = mx + b

y = y coordinate

m = slope (rise/run, up/over, change in y/change in x)

x = x coordinate

b = y intercept (where the line crosses the y-axis.

                                                                                               Blue             Red

1. Write the equation                                                          y = mx + b     y = mx + b

2. Substitute the numbers in the proper place.              y = 2/1 x - 5  y = 3/1x + 3

3. Check for the type of slope- (positive or negative)      y = -2x - 5    y = -3x + 3

   (Downhill slopes are always negative.)
