Answer:

slope intercept form is: y= mx +c

Step-by-step explanation:

Given : linear equation y = -4x + 1, the slope is m = -4

[you can read the slope m ,  from the equation]

rule for perpendicular slope: m1 x m2 = -1

Let the slope in the original equation equal m1, i.e. m1 = -4

therefore, -4 x m2 = -1

m2 = -1/-4

slope of perpendicular line = 1/4

so, y = 1/4 x + 1

In quadrilateral DBCA, name the angles which are consecutive with angle D.
lisov135 [29]

Answer: The consecutive angles with angle D are B and A.

Explanation:

It is given that DBCA is a quadrilateral. Since it is a quadrilateral it means the have 4 vertices and 4 angles D, B,C,A.

The angles are formed in the order of the figure name. If the quadrilateral name is DBCA, So the order of the angles are D,B,C,A. It means the angle immediate after D is B, the angle immediate after B is C, the angle immediate after C is A and the angle immediate after A is D.

If the quadrilateral name is DBCA it means the sides are DB, BC, CA and AD as shown in the figure.

Consecutive angles of D means the angle immediate before and after the angle D.

In the figure there are some types of quadrilateral and from the figure we can easily noticed that the consecutive angles with angle D are B and A.

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by<br> combining the equations.
Citrus2011 [14]

Answer:

(6,-7)

Step-by-step explanation:

subtract them:

-8x - 5y = -13

-4x - 5y = 11

you get

-4x = -24

so x = 6

plug x into the second equation:

-24 - 5y = 11

-5y = 35

y = -7

so your solution is (6,-7).
