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.)
X = 1, x = 7, x = 11.
You can get this by looking at what values of x have the same f(x) value as the g(x)
B...................................
5x+17=-23
Subtract 17 on both sides
5x=-40
Divide by 5 on both sides
X=-8
Double Check:
5(-8)+17=-23
-40+17=-23
-23=-23
