1) The line will need to be vertical down the point of x, meaning draw a line down point x. Perpendicular lines look similar to t’s
2.) Same thing, just draw a line through point O and the line. They should look similar to t’s
Hope this helped!! I understand math can get really hard, soon it’ll all be over :)
Because poop lol
Poop lol = 3.14
If 3.24= Pi then when I eat a peace of pie I eat 3.14
Avani wrote the linear equation y = 5x + 4. Then, she wrote the equation of the line that is perpendicular to y = 5x+ 4 and that passes through (15,–2). If her new equation is in the form , what is the value of b?
- m is the slope
- b is the y-intercept
The equation of a line that is perpendicular to another line always has the opposite reciprocal slope. In the original equation, the slope is 5. The opposite of 5, which refers to the sign, is -5. The reciprocal of -5 is -1/5. That means the slope of the new line is -1/5.
The perpendicular line:
- Has a slope of
- Passes through the point (15, -2)
To find the equation of a line that passes through a specific point, you need to use slope-intercept form.
- y₁ is the y-value of the point
- m is the slope
- x₁ is the x-value of the point
y₁ is -2, m is -1/5, and x₁ is 15.
Substitute the known values into the equation:
Open the parentheses and distribute:
The new equation will be:
Lastly, you need to move the positive 2 to the other side to keep it in y = mx + b form.
The equation of the perpendicular line is:
The value of b is 1.
The slope is 3.
If you go down the line, -2+3=1 and so on, or subtract (7-4 or 1-(-2)), you will come to the conclusion that the slope is 3.
