Answer:

y = -4x + 15

Step-by-step explanation:

slope = (-1 -7)/(4-2) = -8/2 = -4

y = mx + b

7 = -4(2) + b

15 = b

y = -4x + 15

Li graphed the equation y=2x+3. Which table of values did Li use to create her graph?
Natali5045456 [20]

Answer:

See attached picture.

Step-by-step explanation:

To graph the line, start at (0,-3) since b=

-3 in the equation. This is the y-intercept.

Mark this point. From this point, move

down 2 units and to the right 1 unit. Mark

this new point at (1,-1). Connect the points

with a line. See attached picture.

The convex polygon below has 7 sides. find the value of x
Brrunno [24]
The given convex polygon has 7 sides

Hence its sum of interior angles is given by the formula , (number of sides-2)x180°

=> (7-2) x 180°

=> 5 x 180°

=> 900°

The sum of all angles must be equal to 900°

The given six angles are :

139°,126°,106°,129°,141°,112° , x°

=> 139+126+106+129+141+112+x = 900°

=> 753 + x = 900

=> x = 900-753

=> x = 147°

Hence 147° is the required answer.
