Y - (-4) = (5 - (-4))/(2 - (-1)) (x - (-1))
y + 4 = (5 + 4)/(2 + 1) (x + 1)
y + 4 = 9/3 (x + 1)
y + 4 = 3(x + 1)
y + 4 = 3x + 3
y = 3x + 3 - 4
y = 3x - 1

Slope is important; so lets find it; subtract points and stack y/x (2 , 5) (–1, –4) ------- 3 , 9 ; slope = 9/3 = 3 the equation of the line is: y = mx -mPx + Py , where (Px,Py) is any point that is given

and m=slope :) y = 3x -3(2)+5 y = 3x -6+5 y = 3x -1

What is an equivalent expression to q(2a+1)

kvasek [131]

You can distribute the q to both terms to get

$q(2a+1) = q\cdot 2a + q\cdot 1 = 2aq+q$

Which statement is true about the equations-3x 4y 12 and tx 1?

nydimaria [60]

We need to solve -3x+4y=12 for x

Let's start by adding -4y to both sides

-3x+4y-4y=12-4y

-3x=-4y+12

x = (-4y+12)/-3

x= 4/3 y -4

Now substitute 4/3 y -4 for x in 1/4 x - 1/3 y =1

1/4 x -1/3 y =1

1/4 (4/3 y -4) -1/3 y =1

Use the distributive property

(1/4)(4/3 y) + (1/4)(-4) -1/3 y =1

1/3 y -1 - 1/3 y =1

Now combine like terms

(1/3y -1/3y) + (-1) =1

= -1

-1 = 1

Now add 1 to both sides

0=2

So there are no Solutions

The answer is C

I hope that's help Will :)
