Step-by-step explanation:
You posted no answer choices, but a parallel oline has the same slope, so it is in the form
y = 1/5x + b
But b cannot be -1
Answer: x= -3
Step By Step Explanation:
The value of ac is -1
Step-by-step explanation:
Let us revise some rules
- The slope-intercept form of the linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept
- The product of the slopes of the perpendicular lines is -1
∵ The equation of the first line is y = a x + b
- The equation of the line in the slope-intercept form
∴ m = a
∴ The slope of the line = a
∵ The equation of the second line is y = c x + d
- The equation of the line in the slope-intercept form
∴ m = c
∴ The slope of the line = c
∵ The two lines are perpendicular
∵ The product of the slopes of the perpendicular lines is -1
- Multiply the two slopes and equate the product by -1
∴ (a)(c) = -1
The value of ac is -1

In your graphing calculator, you can press 2nd then cos to create cos^-1 and then press 0.5967.
You’re basically doing arccos(0.5967) or cos^-1(0.5967)
Remember to put your calculator into radian mode first.
Your answer will be 0.9314138684 in radian
For degrees it would be 53.36608364
