Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
A horizontal line has a slope of 0. Therefore, our equation would look like:
If y = some constant <em>b</em>, that would be a horizontal line encompassing all <em>x</em> values for the single <em>y</em> value.
∴ Our answer is A.
Answer:
y = (1/3)x - 4
Step-by-step explanation:
Notice that the graph crosses the y-axis at (0, -4). The y-intercept is thus 4, which we often call "b."
If we start at (0, -4) and move to the right along the graph, we see that the first point at which both the change in x and the change in y are integers is (3, -3).
As we go from (0, -4) to (3, -3), x increases by 3 and y increases by 1.
We can then conclude that the slope, m, of this line is
m = rise / run = 1 / 3.
Substituting b = -4 and m = 1/3 into the slope-intercept form of the equation of a straight line, we get:
y = (1/3)x - 4
The answer is 3 losses, or choice B.
Pay attention to the ratios. Each one has a ratio of 9:1.
27/9 is 3. 27:3 is the same as 9:1.
So 3 losses
The formula for volume of a cone is V=(1/3)*h*π*(r^2)
our height is 7.5 feet, and since the length of the base of the cone (diameter) is 22 feet long, the radius is 11 feet long.
(1/3)*7.5*π*(11^2)=302.5*π=950.3
so the volume of the house is about 950 feet cubed.
