Answer:
y = - 5x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 5y = 4 ( subtract x from both sides )
- 5y = - x + 4 ( divide the terms by - 5 )
y = 
x - 
← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 5 , then
y = - 5x + c ← is the partial equation
To find c substitute (- 1, 2) into the partial equation
2 = 5 + c ⇒ c = 2 - 5 = - 3
y = - 5x - 3 ← equation of perpendicular line
To point plots on a graph, take the following steps:
1. Identify the x-coordinates and y-coordinates from the variable/data you have. It should be written in this form: (x, y)
2. Label both axes on the graph(x-axis and y-axis). The x-axis is usually on the horizontal line while the y axis is the horizontal line.
3. Start plotting your first 2 points on both axes (usually the numbers on first row). Plot the x value and also plot the y value at the appropriate points
4. Finally, Continue plotting the numbers by pointing each point on the graph (take them in rows)
Answer:
6 and 4
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
-2 is closer to zero than -2.25, which means -2 is greater than -2.25
