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.

Find the slope and y-intercept of the line. 18x + 2y = –36
Weegy: .Write y =1/4 x + 6 in standard form using integers. A.4x – y = 24 B.–x + 4y = 24 C.–x – 4y = 24 D.–x + 4y = 6 User: The grocery store sells kumquats for $3.75 a pound and Asian pears for $2.25 a pound. Write an equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $22. A. 3.75p + 2.25k = 22 B. 3.75k + 2.25p = 22 C. 3.75 + 2.25 = k D. 3.75k = 2.25p + 22 (More)

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

Solve the system using elimination. 7x + 5y = 15 –6x – 4y = –14 A. (–4, 5) B. (–6, 7) C. (7, –7) D. (5, –4)

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
