Given the list of ordered pairs, identify the y-intercept.

Kipish [7]

The y-intercept is the point (0,-4)

This is the y-intercept because this point has a zero for its x-coordinate, which indicates that this point is staying on the y-axis.

Solve each system by substitution 5.) y= -3x x + y =4

soldier1979 [14.2K]

Answer:

x = -2

y = 6

Step-by-step explanation:

y= -3x

x + y =4

Substitute y = -3x from the first equation into the second equation

x + (-3x) = 4

Combine like terms

-2x = 4

Divide by -2

-2x/-2 = 4/-2

x = -2

Now find y

y = -3x

y = -3(-2)

y = 6

I need this answer pleaseee:(

Answer:

Given - A triangle PMQ

To find - Measure of Q and N

Solution -

In triangle PMQ

Angle p = 37°

Angle M = 78°

Using Angle sum property of triangle :

Sum of all angles of a triangle = 180°

Angle M + Angle p + Angle N = 180°

78 + 37 + N = 180°

115 + N = 180°

N = 180 - 115

N = 65°

In triangle PQR 

Angle p = 37°

Angle R = 65°

Using Angle sum property

Sum of all angles of a triangle = 180°

Angle p + Angle R + Angle Q = 180°

37 + 65 + Q = 180°

102 + Q = 180

Q = 180 - 120

Q = 60°
