Answer:

C. Infinite solutions

Step-by-step explanation:

I'll use the equal value method and make the second equation equal 6 instead of 18, so I have to divide the entire equation by 3

(6x+15y=18)/3 = 2x +5y = 6

The second equation is the same thing as the first one, meaning no matter what value they will equal the same thing, also meaning there are infinite solutions

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
