Answer:

y = -6x — 13

Step-by-step explanation:

use y = mx + b equation and plug in what you know.

5 = -6(-3) + b —> solve for b

b = -13 —> plug in what you know into y=mx+b

What is the equation of the blue line?

zaharov [31]

Answer: y = 3x + 2

Step-by-step explanation:

$\dfrac{x-x_{1} }{x_{2} -x_{1} } =\dfrac{y-y_{1} }{y_{2} -y_{1} }\\$

Let's choose two arbitrary points on the graph.

For example, let these be points with coordinates (1, 5) and (2, 8).

Substitute the coordinates of these points into the above formula and derive the equation of a straight line.

$\dfrac{x-1}{2-1} =\dfrac{y-5}{8-5}\\\\\dfrac{x-1}{1} =\dfrac{y-5}{3}\\\\3(x-1)=y-5\\3x-3=y-5\\y=3x-3+5\\y=3x+2$

Solve each system by substitution.

Assoli18 [71]

This how you set the equation up.
2x + 6 = 3x + 7
Subtract 6 from both sides.
2x = 3x + 1
Subtract 3x from both sides.
-1x = 1
Divide.
x = -1.
Now solve for y by plugging in the variable.
y = 2(-1) + 6
y = -2 + 6
y = 4
So your solution is (-1,4).
I hope this helps love! :)
