Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.
m is the slope, while b is the y-intercept.
Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.
Find the slope of the line shown in the graph using the formula, .
Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)
Let,
Therefore:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Answer:
The length of the diagonal AC=20 cm.
Step-by-step explanation:
From ΔOBP and ΔABC, we have
( O and P are mid points)
∠B=∠B(Common)
Therefore, by SAS rule,
ΔOBP is similar toΔABC
Thus,
⇒
⇒
⇒
⇒
Thus, the length of the diagonal AC=20 cm.
