Slope passes through (4, –6) and m = 3/5 . To find the equation, we need to find the y intercept, which is when x = 0. For every unit of x that decreases, y will decrease by 3/5. So when x moves from 4 to 0, y will decrease by 12/5, so the y intercept is at (0, -8 2/5).

So the equation of the line is y = (3/5) x - 8 2/5.

So the equation of the line is y = (3/5) x - 8 2/5.

18x + 2y = –36 in y = mx + b form is y = -9x - 18, where m stands for slope. Therefore, the slope is -9.

To find the y-intercept, let x = 0.

y = -9x - 18;

y = -9(0) - 18;

y = 0 - 18 = -18

Slope: -9

Y-intercept: -18

To find the y-intercept, let x = 0.

y = -9x - 18;

y = -9(0) - 18;

y = 0 - 18 = -18

Slope: -9

Y-intercept: -18

The solution set for 7x + 5y = 15, –6x – 4y = –14 is (5, –4).

(7x + 5y = 15) * 6;

42x + 30y = 90;

(–6x – 4y = –14) * 7;

-42x - 28y = -98;

(42x + 30y = 90) + (-42x - 28y = -98);

2y = -2; y = -8/2; y = -4;

7x + 5y = 15;

7x + 5(-4) = 15;

7x - 20 = 15;

7x = 15 + 20;

7x = 35;

x = 35/7; x = 5

(7x + 5y = 15) * 6;

42x + 30y = 90;

(–6x – 4y = –14) * 7;

-42x - 28y = -98;

(42x + 30y = 90) + (-42x - 28y = -98);

2y = -2; y = -8/2; y = -4;

7x + 5y = 15;

7x + 5(-4) = 15;

7x - 20 = 15;

7x = 15 + 20;

7x = 35;

x = 35/7; x = 5
