Type an equation for the line

Thepotemich [5.8K]

Answer:

$y=-\frac{2}{3}x+1$

Step-by-step explanation:

Let the equation of the line given in the graph is,

y = mx + b

Where 'm' is the slope of the line

And 'b' represents the y-intercept

Since slope of a line passing through two points $(x_1, y_1)$ and $(x_2,y_2)$ is modeled by,

m = $\frac{y_2-y_1}{x_2-x_1}$

If this line passes through (-3, 3) and (3, -1),

m = $\frac{3+1}{-3-3}$

m = $-\frac{4}{6}$

= $-\frac{2}{3}$

And 'b' = 1

Equation of this line will be,

$y=-\frac{2}{3}x+1$

10x - 10y = 1 x = y - 3 solve the system of equations by substitution. a. (-29/20, 31/20) b. (1/2, 2/5) c. no solution d. coinci

First you'd substitute x= y-3 in the first equation.

10(y-3) -10y= 1

10y - 30 -10y= 1

The y's cancel each other out, so you're left with -30= 1. That means there's no solution :)
