Answer:
Equation of the line that passes through the point (-2,7) and has a slope of zero is given as

Step-by-step explanation:
Equation of line is given as
-----------(1)
Here

Substituting values in equation (1)

Answer:
bc= 6
Step-by-step explanation:
since the triangles are similar, the sides are in a ratio
xz/ac = 20/4 (5:1)
yx/ba = 15/3 (5:1)
yz/bc = 5:1 = 30/6
Answer: 1100
Step-by-step explanation: mark x for the total sum.
0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x
495= 0.45x. X= 495/0.45

This line is in the format
, where
is the slope.
A horizontal line has a slope of
.
A vertical line has an undefined slope.
A positive slope makes the line go upwards and to the right.
<em>A negative slope makes the line go downwards and to the right.</em>
