Answer:
Step-by-step explanation:
You want the slope-intercept equation of the line through (2, 2) and parallel to the line through (-1, 6) and (1, 5).
<h3>Slope</h3>
The parallel line will have the same slope. The slope is given by the equation ...
m = (y2 -y1)/(x2 -x1)
m = (5 -6)/(1 -(-1))
m = -1/2
<h3>Intercept</h3>
We need to find the y-intercept of the desired line. Solving the equation for "b", we get ...
y = mx +b
b = y -mx . . . . . . . subtract mx to find b
b = 2 -(-1/2)(2) . . . . use m=-1/2 and (x, y) = (2, 2)
b = 2 +1
b = 3
The equation we want is ...
y = -1/2x +3
Answer:
French and Spanish = 8 , French = 23, Spanish = 15
Step-by-step explanation:
60 - 14 = 46
31+23 = 54
54-46 = 8
31- 8 = 23
23 - 8 = 15
15 + 23+8+14= 60
The way to use the distance formula to classify quadrilateral include:
- Use the distance formula to measure the lengths of the sides.
- Use the slope to check whether the sides are perpendicular and form right angles.
- Use the slope to check whether the diagonals are perpendicular to each
<h3>How to illustrate the information?</h3>
The steps to calculate the perimeter and area of a polygon:
Step 1: Plot the given points on the graph.
Step 2: Connect the points and identify the figure.
Step 3: Determine lengths by counting the grid lines.
Step 4: Use a formula to calculate the perimeter and area if one exists.
Step 5: If there are no formulas for a figure, the perimeter can be calculated by summing the lengths of the sides. We might estimate the area without an area formula by counting the number of small squares enclosed.
