Answer:

Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
The slope can be found from two points.

The two points from the graph are (1, 9) and (2, 12).
Plugging in the values and evaluating.



The slope of the line is 3.
The y-intercept of the line is where the line cross the y-axis.
The line crosses the y-axis at (0, 6).

The slope-intercept form of the line is:

Answer:
Step-by-step explanation:
Step 2: 2.8z - 3.4z - 7.2 + 6.6
Step 3: -0.6z - 0.6
-7 (-15w + 21) + 3(18 - 27w)
step 1: 105w - 147 + 54 - 81w
Answer:
The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.
