What would be the slope for (-4,-7) (-6,4)

Sliva [168]

Answer: $\frac{11}{-2}$

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

$\frac{y2-y1}{x2-x1} =$ m

so when using that formula with the cords, you get

$\frac{4-(-7)}{-6-(-4)}$

and then subtract everything and you'll get

$\frac{11}{-2}$

Solve the simultaneous equation: 2x - y= 2 3y= 4x - 5

Ronch [10]

Answer:

x = $\frac{1}{2}$ , y = $-1$

Explanation:

2x - y= 2

3y= 4x - 5

Make y the subject:

2x - y= 2

-y = 2 - 2x

y = 2x - 2 .........equation 1

3y= 4x - 5

y = (4x - 5)/3 ........equation 2

From equation 1 and 2 solve them simultaneously:

→ (4x - 5)/3 = 2x - 2

→ 4x - 5= 3(2x - 2)

→ 4x - 5 = 6x - 6

→ 6x - 4x = -5 + 6

→ 2x = 1

→ x = 1/2

if x is 1/2, then y: 2x - 2

→ 2(1/2)-2

→ -1
