Third option.
Use y = mx + b (slope-intercept form) to get
y = (1/3)x + b.
Then plug in the point (1,-2) for x and y to figure out b...
-2 = (1/3)(1) + b
-2 - 1/3 = b, so b = -7/3
Now you have y = (1/3)x - 7/3. Convert to standard form by multiplying each term by 3 to get
3y = x - 7. Then move the 3y to the other side to get 0 = x - 3y - 7
Answer:
= - 12
Step-by-step explanation:
Given that:
= 3(x - 4) + 2x - x2
Now put x=5
= 3(5 - 4) + 2(5) - (5)^2
= 3(1) + 10 - 25
= 13 - 25
= - 12

Answer:
Sin^2 x + Cos^2 x = 1
Sin^2 x = 1 - 4 / 9 = 5 / 9
Sin x = / 3
Tan x = Sin x / Cos x = ( / 3) / (2 / 3) = / 2
Answer:
C
Step-by-step explanation:
Answer: y = -2x + 1 or y +2x - 1 = 0
Step-by-step explanation
Recall, equation of a line passing through two coordinates is
y - y₁ = y₂ - y₁ ( x - x₁ )
₋₋₋₋₋₋₋₋ x
x₂ - x₁
note , (x₁ = -3), (x₂ = 1), (y₁ = 7), (y₂ = -1)
Now substitute for those values in the above equation
y - (7) = -1 - 7
------ X ( x - (-3)
1 - (-3)
y - 7 = -8/4 X ( x + 3 )
y - 7 = -2(x + 3 )
y - 7 = -2x - 6
The equation now
y = -2x -6 + 7
y = -2x + 1 or
y + 2x - 1 = 0.
