Answer:
y = 7/3x +13/3
Step-by-step explanation:
The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/(-3/7) = 7/3
The y-intercept of the perpendicular line can be found from ...
b = y -mx
b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3
Then the slope-intercept equation of the perpendicular line is ...
y = mx +b
y = 7/3x +13/3
_____
<em>Additional comment</em>
You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...
y -k = m(x -h)
For our perpendicular line, the equation is ...
y +5 = 7/3(x +4)
Well, let's convert the yards into feet. 1 yard = 3 feet. So Berkley has 10 pieces of ribbon that are each 6 feet, that's a total of 60 feet. 8 * 3 = 24, so she uses a total of 24 feet. Subtract the total amount she used from what she has: 60 - 24 = 36. Berkley has 36 feet of ribbon left.
Answer:
true
Step-by-step explanation:
use the pythagorean theorem
The graph would look like a downward line starting from zero
domain is -infinity to infinity and so I'd the range
