For perpendicular the way you find it is by flipping the fraction. and adding a negative. remember that whole number are fractions divided by 1.
so what you would get is
y=5x+a
then we put in the points into our x and y.
2=5(1)+a
now solve
2-5=a
a=-3
Now you will put into standard form
y=5x-3
45mins ÷ 15pages = 3
so she reads 3pages per minute
3pages × 60minutes = 180
she read 180pages in 60minutes
hope this helps
The dimensions of the building on the drawing would be 92.5 inches by 100 inches.
Explanation:
if 1 inch = 8 feet, then you just subtract 8 by 740 and 800 to get the dimensions.
Answer: the x-intercept is (-10,0), the y-intercept is (0,45/2)
Explanation:
First, we need to determine the function describing the line.
From the table, it is obvious that the y values increase by 9 every increase of 4 of the x values. So, the slope is 9/4 and the function looks like this:

with the y-intercept (or bias) b still unknown. This can be determined by using one of the point from the table, like so:

The above function form makes it easy to read off the y-intercept, which is (0,45/2) or (0,22.5). The x-intercept is obtained by setting y = 0 and solving for x:

The x-intercept is (-10,0)
SinC=(8/17)
solve for C = arcsin(8/17)
