Ax + By + C = 0
A. 3x + 5y + 45 = 0
3x + 5(0) + 45 = 0
3x = -45
x = -45/3......x int.....-C/A
x = -15
B. To find the x intercept, u must sub in 0 for y and solve for x
C. This is not true for a horizontal line because u can't sub in 0 for x because a horizontal line never crosses the x axis and therefore, does not have an x axis.
D. y int is -C/B....u find this by subbing in 0 for x and solving for y
3x + 5y + 45 = 0
3(0) + 5y + 45 = 0
5y = -45
y = -45/5......y int = -C/B
y = -9

Answer:
17x - 15y
Step-by-step explanation:
(10x - 7y) + (7x -8y)
17x - 15y
The second one : f(x) = x+3, x<0
= 3, x>=0
