Answer:

A: -6.5

Step-by-step explanation:

Take two points that we already know are on the line and find the slope

I used:

(4, -10) and (7, -30)

X1 (first x coordinate): 4

Y1 (first y coordinate): -10

X2 (second x coordinate): 7

Y2 (second y coordinate): 30

These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.

Use (Y2-Y1)/(X2-X1)

(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.

The closest answer to that is A.

A line is parallel to y = 5x + 9 and
ryzh [129]
<h3>Answer:    y = 5x + 7</h3>

Work Shown:

y - y1 = m(x - x1)

y - (-3) = 5(x - (-2))

y + 3 = 5(x + 2)

y + 3 = 5x + 10

y = 5x + 10 - 3

y = 5x + 7

The equation is now in slope intercept form y = mx+b with m = 5 as the slope and b = 7 as the y intercept. Plugging x = -2 into this equation will lead to y = -3.

Side note: parallel lines have equal slopes but different y intercepts.

PLEASE ANSWER THIS RIGHT ASAP
Anastaziya [24]

Answer:

x=9

Step-by-step explanation:

23=7/9(6x-36)+9

Distribute 7/9.

23=14/3x-28+9

Add.

23=14/3x-19

Add 19 to both sides of the equation.

42=14/3x

Divide 14/3 from both sides of the equation.

X=9

Hope this helps :)

HELP DUE IN 15 MINS! <br> Solve for x in the parallelogram below:<br><br> X=??
malfutka [58]

Answer:

x = 4

Step-by-step explanation:

Consecutive angles in a parallelogram are supplementary, sum to 180°, so

14x + 6 + 118 = 180

14x + 124 = 180 ( subtract 124 from both sides )

14x = 56 ( divide both sides by 14 )

x = 4
