Answer:
y = 4x -5
Step-by-step explanation:
Gradient is also known as slope . The gradient of a line is represented by the equation
Slope (m) = y - y1/ x - x1
Where m = 4 , x1= 1 and y1 = -1
Imputing the values into the equation
m = y - y1/ x - x1
4 = y - -1/x - 1
Cross multiply, we have
y + 1= 4(x - 1)
Expand
y+1= 4x - 4
Subtract 1 from both sides
y+1-1= 4x -4-1
y = 4x -5

Answer:
19 dollars
Step-by-step explanation:
What you have to do is find a way to make sure each book is the same price and it lowers to 16. First rule out 1-10. It wouldn't be possible. Next, try and start with the even numbers (16, 18, 20, and so on). It can't be twenty because 20 x 8 equals 160 and you're left with 16 dollars, not 8. so it's either 14, 15, 16, 17, 18, or 19. I calculated with my calcuator that it's not any of the answers but 19. So try it out!
Triangle D
Because the Pythagorean Theorem is only used with a RIGHT triangle
