4. Given the line 7x + 6y = 5, do the following.
Annette [7]

Answer:

a- Slope-intercept form (y =  \frac{-7 x}{6\\} + \frac{5}{6})  ::=> 1

b- Slope of Line =  m = \frac{-7}{6}    : From Equation 1

Step-by-step explanation:

a- We have following equation:

7x + 6y = 5

Here if we re-arrange for y:

6y = 5 -7x  :: Compare it with y = mx + b

y =  \frac{-7 x}{6\\} + \frac{5}{6}

b-Compare  y = mx + b and y =  \frac{-7 x}{6\\} + \frac{5}{6}

m= -7/6 and Slope of lines parallel to the given line is shown in the equation
