Answer:
y - (-7) = 7(x - 4)
Step-by-step explanation:
The given points are (4. -7) and (5, 0).
The point-slope equation of a line is
y - y1 = m(x - x1),
where (x1, y1) is a point on the line, and m is the slope.
m = (y2 - y1)/(x2 - x1) = (-7 - 0)/(4 - 5) = -7/(-1) = 7
You can use either point for (x1, y1). I will use point (4, -7).
y - (-7) = 7(x - 4)
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:
The answer is A.
