A decimal an integer a whole number
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct
Answer:
Step-by-step explanation:
Cube = Height x Width x Depth
Cylinder = Area of the bottom x Height (Area of the bottom =
)
Cone =
Area of the bottom x Height (Area of the bottom =
)
Pyramid = Base Area x Pyramid height
Right rectangular pyramid = Base length x Base width x Pyramid height
Sphere =
(r is the radius of the sphere)

First you need to find the slope of the line containing those 2 points using the slope formula. Filling in with our info we have

. So the slope is -1.5. Now we need to find out the rest of the info, mainly the y-intercept. The line appears to go through the y axis at (0, 0), but let's make sure. We will use the slope we just found and one of our points to solve for the y-intercept. I picked point (4, -6). Filling in to solve for b we get -6 = (-1.5)(4) + b. Doing the multiplication on the right gives us -6=-6 + b. Add 6 to both sides to get that b = 0. Now let's use that and the slope we found to rewrite the equation in slope-intercept form. y = -1.5x + 0 or y = -1.5x and there you go!
