To deliver what is being asked of the given above, solve first for the slope of the line. Given two points the slope is calculated by,
m = (y2 - y1) / (x2 -x1)
m = (14 - 5) / (-2 - 1) = -3
Use the point - slope to write the equation of the line,
y - y2 = m(x - x2)
y - 14 = -3(x - -2)
<em> y = -3x + 8</em>
Therefore, the answer is letter D.
Answer:
3/2
Step-by-step explanation:
In order to find the slope with two points, you use this formula:
y2-y1 / x2 - x1.
y2 is 5 and y1 is -4. 5 - -4 = 9
x2 is 2 and x1 is -4. 2 - - 4 = 6
9/6 = 3/2.
Answer:
x = 114
Step-by-step explanation:
114 and x are vertical angles, therefore they are congruent.
Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x
