Please help me with number 4 it’s been due

1. 4y = 3x - 8

2.y-7 = -2(x + 4)

Step-by-step explanation:

1. The general equation form is;

y = mx + b

m is slope b is y-intercept

so we have;

y= 3/4x - 2

Multiply through by 4

4y = 3x -8

2. The point-slope form is;

y-y1 = m(x-x1)

y-7 = -2(x + 4)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
