Plz help urgent so easy will give brainliest mark for the first answer given!!

timama [110]

Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

4x + 9y = -9

By converting this equation into y-intercept form,

9y = -4x - 9

$y=-\frac{4}{9}x-\frac{9}{9}$

$y=-\frac{4}{9}x-1$

By comparing this equation with y = mx + b

Here, m = Slope of the line

b = y-intercept

Slope of the equation (m) = $-\frac{4}{9}$

y-intercept (b) = -1

8). Equation of the line is,

5x + 3y = 12

3y = -5x + 12

$y=-\frac{5}{3}x+\frac{12}{3}$

$y=-\frac{5}{3}x+4$

Slope of the line = $-\frac{5}{3}$

y-intercept = 4

4 = y - x

2. 2x+4y = 10

x+4y = 5

x+y = 5/4
