A line passes through the points (–3, –4) and (6, 2).

-3

Step-by-step explanation:

The x-intercept is 3, here's why

First, you need to get the slope

y2-y1

x2-x1

You should get 2/3

Next, you need to use y=mx+b

y= 2/3x+b

2= 2/3(6)+b       You get 6 and 2 from the coordinates

Once this is worked out you'll get y=2/3x-2

To get the x intercept you need to set y equal to 0

0=2/3x-2

Add 2 to each side

0-2 = 2/3x

Multiply each side by 3/2 to isolate x

-2 *3/2 = 2/3x * 3/2

-3 =x

The x intercept is -3

Hope this helped, Brainliest appreciated :)
