Answer: Point-slope form equation:
Using the point-slope form equation, which is y - y₁ = m(x - x₁), where (x₁, y₁) is the given point and m is the slope, we can substitute the given values to find the equation.
Point = (-9, 3)
Slope = -2/3
Using the point-slope form equation:
y - 3 = (-2/3)(x - (-9))
Simplifying:
y - 3 = (-2/3)(x + 9)
Expanding:
y - 3 = (-2/3)x - 6
Rearranging:
y = (-2/3)x - 3
Therefore, the equation of the line is y = (-2/3)x - 3.
Parallel to y = 5x - 2:
The parallel line will have the same slope (5) as the given line because parallel lines have the same slope. The y-intercept is given as -3.
Using the slope-intercept form equation, which is y = mx + b, where m is the slope and b is the y-intercept, we can substitute the given values to find the equation.
Slope = 5
Y-intercept = -3
Therefore, the equation of the line is y = 5x - 3.
Perpendicular to y = (1/2)x + 1:
To find the perpendicular line, we need to take the negative reciprocal of the slope (1/2). The negative reciprocal of a number is obtained by flipping the fraction and changing the sign.
The given line has a slope of 1/2, so the perpendicular line will have a slope of -2 (negative reciprocal of 1/2). The y-intercept is given as 9.
Using the slope-intercept form equation, which is y = mx + b, where m is the slope and b is the y-intercept, we can substitute the given values to find the equation.
Slope = -2
Y-intercept = 9
Therefore, the equation of the line is y = -2x + 9.
