For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...

5-2
——. = 3/4
11 - 7


For question 5: input the values of x,y and the gradient into the equation of a line.....

y = mx+ c

-8 = 3(-2) + c

-8 = -6 + c

-2 = c

therefore:

y = 3x - 2

Hope this helps! Any questions let me know :)

What is the equation of the line that has a slope of -3 and passes through the point (4,6)?
garri49 [273]

Answer:

y = -3x + 18

Step-by-step explanation:

y = mx + b

m = -3

6 = (-3) * 4 +b

b = 6 - (-3) * 4

b = 6 +12

b = 18

y = -3x + 18

Let:T : ℝ3→ℝ3 be the transformation that projects each vector x=​(x1​,x2​,x3​)onto the plane
dangina [55]

Answer:

Step-by-step explanation:

A linear transformation must satisfy the following properties.

- T(0) = 0.

- For vector a,b then T(a+b) = T(a) + T(b).

- For a vector a and a scalar r, it must happen that T(ra) = rT(a)

In this case we have that T(a,b,c) = (a,0,c).

Note that T(0) = T(0,0,0) = (0,0,0) = 0. So, the first property holds.

Let a=(a_1,a_2,a_3), b=(b_1,b_2,b_3). Then

T(a+b) = T((a_1+b_1,a_2+b_2,a_3+b_3)) = (a_1+b_1,0,a_3+b_3) = (a_1,0,a_3)+(b_1,0,b_3) = T(a) + T(b)

So the second property holds.

Finally, let r be a scalar and let a=(a_1,a_2,a_3). Then

T(ra) = T((ra_1,ra_2,ra_3)) = (ra_1,0,ra_3) = r(a_1,0,a_3)= rT(a)

So, the three properties hold, and therefore, T is a linear transformation.
