What is the slope of a line perpendicular to the<br> graph of the equation 5x - 3y = 2?)
Advocard [28]

The slope of a line perpendicular to the

graph of the equation 5x - 3y = 2 is -3/5.

<h3>How to find the slope of a line?</h3>

given that the equation is 5x - 3y = 2.

now write the equation in standard form y = mx + b

then -3y = 2 - 5x

y = -2/3 + 5x/3

y = 5/3x - 2/3

m 1*m 2 = - 1 is the formula for the slopes from a pair of perpendicular lines. where the slopes of the lines are m 1 and m 2.

Here m1 = 5/3 and m2 = -3/5.

Hence,the slope of a line perpendicular to the

graph of the equation 5x - 3y = 2 is -3/5.

The missing step in this proof is ∠BAC ≅ ∠BDE ⇒ answer D

Step-by-step explanation:

If two triangles are similar by SAS, then their corresponding angles are

equal and the 3rd corresponding sides have constant ratio

In the two triangles ABC and DBE:

  • ∠ABC ≅ ∠DBE
  • \frac{AB}{DB}=\frac{BC}{BE}

Then the two triangles are similar

From similarity:

∠BAC ≅ ∠BDE

∠BCA ≅ ∠BED

∴ The missing step is ∠BAC ≅ ∠BDE

The missing step in this proof is ∠BAC ≅ ∠BDE
