Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
Familias que usan 2 computadoras sera una para los padres y otra para sus hijos para sus tareas del colegio y las cque no tienen tendran que ir a un ciber las que tienen 4 sera aun mejor y mas rapido hacer sus tareas
Answer:
the answer is c
Step-by-step explanation:
because if the surgery has a 92% success rate and the splints have a 72% success rate then surgery would be recommended because it has a higher success rate
Scale factor is a ratio, you have to remember that. divide the lengths and you will see a constant cratio
y=ax+b and y=cx+d, these lines are parallels if a = c
2) a) y = 3x+9, the two lines are y = 3x-4 and y = 3x+5
<span>b) y = -5x+6, the two lines are y = -5x+4 and y = -5x-2
</span>c) y = -7x+8, the two lines are y = -7x-9 and y = <span>-7x+7
same method with the d e and f
3) </span><span>y=ax+b and y=cx+d, these lines are perpendicular if a x c=-1
a) y=3x+7, the two lines are y= (-1/3 )x +2, and y= (-1/3)x-6 </span><span>
b) </span>y= -5/6x-2, the two lines are y= (6/5)x -2, and y= (6/5)x+13<span>
c) </span>y= - 5x+8, the two lines are y= (1/5)x - 32, and y= (<span>1/5 )x+11
the same method for d e and f
4) coordinates of the midpoints
a) (0, 0) and (5, 15)
the midpoints is ((0+5) / 2, (0+15)/2)= (5/2, 15/2)
b) (2, 4) and (6, -5)
</span><span>the midpoints is ((2+6) / 2, (4-5)/2)= (4, -1/2)
</span>c) (3,5) and (7,5)
<span>the midpoints is ((3+7) / 2, (5+5)/2)= (5, 5)
</span>the same method for d e and f
