Find the equation of a line that passes through these two points

Sati [7]

Answer:

y = -2x + 2

Step-by-step explanation:

The equation of a line is y = mx + b.

First we want to find m, the slope. We can used the coordinates to do so: $m = \frac{6-(-4)}{-2-3}\\m = \frac{10}{-5}\\m = -2$

Now we know that the equation is y = -2x + b. We can plug in the coordinate (3, -4) to find b.

$y = -2x + b\\-4 = -2(3) + b\\-4 = -6 + b\\b = 2$

So the equation is y = -2x + 2.

In the equation y= -2x -3 over 5, identify the slope, the y-intercept, and whether the line is rising, falling, horizontal, or v

Hoochie [10]

Answer:

Slope = -2

y-intercept = -3/5

Falling

Step-by-step explanation:

$y= -2x - \frac{3}{5} \\ y = mx + b$

m = Slope = -2

y-intercept = b =

$- \frac{3}{5}$

The slope of the equation has a negative number so the graph is falling
