Answer:
<h2>x = 4</h2>
Step-by-step explanation:
A line with undefined slope is a vertical line.
An equation of a vertical line: x = a (a - real number).
Each point on a line x = a has coordinates (a, b) (b - any real number).
We have the point (4, 0) → x = 4
Answer:
see explanation
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 )
y = x - 9 ← is in slope- intercept form
with slope m =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line.
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y = x - 12 ← equation of parallel line
Answer:
y = m x + b equation of straight line
Slope = (y2 - y1) / (x2 - x1) = (-3 - 1) / ((7 - (-5)) = -4 / 12 = -1 / 3
y = -x / 3 + b since m is defined above
lf y = 7 then x = -5 given
7 = 5/3 + b
b = (21 - 5) / 3 = 16 / 3 = 5 1/3
y = -x / 3 + 5 1/3
Check: Use point x = -5
y = 5/3 + 16/3 = 21 / 3 = 7 correct
My answer is C. So good luck!
