I really need help it’s slope and I’m very confused

abruzzese [7]

Slope formula is y=mx+b so m is the slope and b is the y-int all u do is replace the numbers with the letters and they give u the formula which would be y=-8x-3

Work out the length of ab, give your answer to 3 significant figures

Aleksandr [31]

Answer:

D = 9.85 units

Step-by-step explanation:

A (1,7) and B(10,3)

Using Distance Formula to find the length

=> Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

=> D = $\sqrt{(10-1)^2+(3-7)^2}$

=> D = $\sqrt{(9)^2+(-4)^2}$

=> D = $\sqrt{81+16}$

=> D = $\sqrt{97}$

=> D = 9.85 units (Upto 3 sfs)

Find a solution to the system. Make sure to write as a coordinate.

RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a system of equations.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, $x=2y-4$ , into the value for x in the second equation. Now, the second equation looks like this:

$2*(2y-4)+y=7$

We simplify and solve for y:

→ $4y-8+y=7$

→ $5y=15$

→ $y=3$

Now, we plug in the value for y, which is 3, into either equation. I will just use the first equation:

→ $x=2*3-4$

→ $x = 2$

Let me know if my explanation is unclear.
