Write the standard form equation of the line that passes through the point p and is parallel to the line l.
p : (-1, 0)
l : y = (8/3)x – (17/3)
Write the standard form equation of the line passing through these two points.
p1 : (0, -3)
p2 : (3, -5)
Graph the following equation.
Let’s break down your questions step by step.
### 1. Standard Form Equation of the Line Parallel to Line l
First, we need to find the slope of the given line l, which is in slope-intercept form:
( y = frac{8}{3}x – frac{17}{3} )
Here, the slope (m) is ( frac{8}{3} ). Since parallel lines have the same slope, the slope of the line we need to find is also ( frac{8}{3} ).
Next, we can use the point-slope form of the equation of a line, which is:
( y – y_1 = m(x – x_1) )
Where ( (x_1, y_1) ) is the point p (-1, 0).
Substituting in the values:
( y – 0 = frac{8}{3}(x + 1) )
( y = frac{8}{3}x + frac{8}{3} )
To convert it to standard form ( Ax + By = C ), we will clear the fraction:
Multiply everything by 3:
( 3y = 8x + 8 )
Rearranging gives:
( -8x + 3y = 8 )
Multiplying through by -1, we get:
Let’s tackle your questions one by one.
1. Write the standard form equation of the line that passes through the point p and is parallel to the line l.
First, let’s identify the slope of the given line l, which is in slope-intercept form ( y = mx + b ). Here, the slope ( m ) is ( frac{8}{3} ).
Since the line we want is parallel, it will have the same slope. So, the slope of our desired line is also ( frac{8}{3} ).
Using the point-slope form of a line’s equation, which is ( y – y_1 = m(x – x_1) ), we can substitute ( p(-1, 0) ) into the equation:
[
y – 0 = frac{8}{3}(x + 1)
]
Expanding this gives:
[
y = frac{8}{3}x + frac{8}{3}
]
To convert this to standard form ( Ax + By = C ), we rearrange:
[
-frac{8}{3}x + y = frac{8}{3}
]
Multiply through by 3 to eliminate the fraction:
[
-8x + 3y = 8
]
We can multiply the entire equation by -1 to get:
[
8x – 3y = -8
