Answer:
Step-by-step explanation:
Equations in the given options are linear, so the table given represent a linear function.
Let the equation of the linear function is,
y = mx + b
Since this equation passes through (0, 0),
0 = m(0) + b
b = 0
Therefore, equation of the line will be,
y = mx
Slope of the line passing through (10, 8) and (5, 4),
m =
=
=
Therefore, equation of the line will be,
Option (2) will be the answer.
<h3>The actual height of building is 37.5 feet</h3>
<em><u>Solution:</u></em>
Given that,
The drawing of a building shown below has a scale of 1 inch to 30 feet
1 inch = 30 feet
The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches
<em><u>Thus actual height is given as:</u></em>
height = 1.25 inches
<em><u>The actual base is given as:</u></em>
base = 0.75 inches
Thus actual base is 22.5 feet
It is 71 because 0 is less than 5, so it stays the same.
Answer:
y = -3x + 7
Step-by-step explanation:
If the line is parallel, it will have the same slope. So, this line will have a slope of -3.
Plug in the slope and given point into y = mx + b, and solve for b:
y = mx + b
4 = -3(1) + b
4 = -3 + b
7 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = -3x + 7
So, the equation is y = -3x + 7
