Find the slope (m) by using Y2-Y1/X2-X1
Y2 = -1
Y1 = 7
X2 = 4
X1 = 2
(-1 - 7)/((4-2) = -8/2 = -4
Use the point-slope formula to determine the equation. You only need to use one set of points. (2,7) in this case.
(y-Y1) = m(x-X1)
(y - 7) = -4(x - 2)
y-7=-4x + 8
y= -4x + 15
15, 20, and 25 are a Pythagorean triple, (225+40=625) thus they form a right triangle. The shortest altitude of any right triangle is going to be that of the hypotenuse. All three of the right triangles formed by the altitude on hypotenuse are similar. Thus 15:25 = a:10.
a=6.
Answer:
y = -3
Step-by-step explanation:
A horizontal line has all the same y values, but changing x values
y must equal -3 all the time if it goes through (3,-3)
y = -3
The answer is 20, I hope this helped :)
