Hey can anybody help me

What is the slope of the line that passes through (-2, 7) and (4, 9)?

Bond [772]

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-7}{4-(-2)}\implies \cfrac{9-7}{4+2}\implies \cfrac{2}{6}\implies \cfrac{1}{3}$

3/10 divided by -1/3

Snezhnost [94]

Answer:

-9/10

Step-by-step explanation:

Find the LCM of 10 and 3: 30
Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
Re-write the fractions: 9/30 ÷ -10/30
9/30 ÷ -10/30 = 9/30 × -30/10
9/30 × -30/10 = -270/300
$-\frac{270}{300} = -\frac{9}{10}$

I hope this helps!

Answer:

y = 9

Step-by-step explanation:

since opposite sides are congruent and opposite angles are conguent, we use an equal sign

2y + 9 = 27

Step 1: Subtract 9 from both sides.

2y+9−9=27−9

2y=18

Step 2: Divide both sides by 2.

2y/2 = 18/2

y = 9
