Ok theres two questions i need the equation and answer. 1. write an equation of the line in slope intercept form that has a slope -2/3 and has a y-intercept of -42. write and equation of a line in slope intercept form that passes through the points (3 , -2) and (1 , 4)

1)   y = -2/3x - 4

2)  y = -3x + 7

Step-by-step explanation:

1)  Plug in the slope (m) and y intercept (b) into the equation

     y = mx + b

     y = -2/3x - 4

2)  Find  the slope (m)  m = y₂ - y₁/ x₂ - x₁

                                      m =  4 - (-2)/1 - 3

                                      m =  6/-2

                                     m = -3

   Then find the y intercept (b) by plugging x, y and m into y = mx + b (you can choose either point given

4 = -3 ( 1) + b

4 = -3 + b

Add 3 to both sides

7 = b

So now you know  m = -3 and b = 7  

Plug into y = mx + b

                y = -3x + 7

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
