Answer:
y = 12x/5 - 39/5.
Step-by-step explanation:
The equation of the straight line is given by the following formula:
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1); where (x, y) is the general point, (x1, y1) is the first point on the line, and (x2, y2) is the second point on the line.
Given that (x1, y1) = (2, -3) and (x2, y2) = (7, 9):
(y - (-3))/(x - 2) = (9 - (-3))/(7-2).
(y + 3)/(x - 2) = 12/5.
Cross multiplying:
5*(y + 3) = 12*(x - 2).
5y + 15 = 12x - 24.
5y = 12x - 39.
y = 12x/5 - 39/5.
This the equation of the line in the y = mx + c form!!!
Answer:
the answer to the question is -1
Addition because you add them together to find the total
19)
6/x = x/12
x^2 = 72
x = √72
x = 6√2
y^2 = 12^2 + (√72)^2
y^2 = 144 + 72
y^2 = 216
y = 6√6
21)
14 - 8 = 6
y/8 = 6/y
y^2 = 48
y = √48
y = 4√3
x^2 = 6^2 +(√48)^2
x^2 = 36 + 48
x^2 = 84
x = √84
x = 2√21
