Answer:
Step-by-step explanation:
These equations are all written in slope-intercept form, so the question is relatively easy to answer. These rules apply.
- if slopes are different: 1 solution
- if slopes are the same and y-intercepts are different, 0 solutions
- if slopes are the same and y-intercepts are the same, infinitely many
1. y=-6x-2; y=-6x-2 --- infinitely many
2. y=0.5x+5; y=0.5x+1 --- zero
3. y=0.25x-2; y=5x-4 --- one
4. y=2x+3; y=4x-1 --- one
5. y=2x+1.5; y=2x+1.5 --- infinitely many
6. y=-x-3; y=-x+3 --- zero
_____
Slope-intercept form is ...
y = mx +b
m is the slope
b is the y-intercept
Answer:
the equation of the line will be:
Step-by-step explanation:
Equation of line: x + y = 6
We need to write an equation for the perpendicular line that goes through
(5, 1).
The equation will be in slope-intercept form where m is slope and b is y-intercept
Finding Slope:
Equation of line given is: x+y=6
Writing it in slope-intercept form:
The slope of this line is m = -1 (By comparing it with we get m = -1)
Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e.
So, slope of required line will be: m=1
Now, using the point (5,1) and slope m=1 we can find y-intercept
So, we get y-intercept b = -4
Now, the equation of required line, having slope m=1 and y-intercept b = -4
So, the equation of the line will be:
