your x-intercept is 3 and I don't know why I have to do 20 characters for an answer that involves 3 words and 1 number

Answer:

Point-Slope form:

The equation of line is given by:

[tex]y-y_1 = m(x-x_1)[/tex]

where,

m is the slope of the line and [tex](x_1, y_1)[/tex] is the point on the line.

As per the statement:

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

Using slope formula:

[tex]\text{Slope(m)} = \frac{y_2-y_1}{x_2-x_1}[/tex]

then;

[tex]m = \frac{2-(-4)}{6-(-3)}=\frac{6}{9} = \frac{2}{3}[/tex]

Substitute the given values and m = 2/3 we have;

[tex]y-(-4) = \frac{2}{3}(x-(-3))[/tex]

⇒[tex]y+4 = \frac{2}{3}(x+3)[/tex]

We have to find the  x-intercept of this line.

x-intercept:

Substitute y =0 and solve for x:

then;

[tex]0+4 = \frac{2}{3}(x+3)[/tex]

⇒[tex]4 = \frac{2}{3}(x+3)[/tex]

⇒[tex]2 = \frac{1}{3}(x+3)[/tex]

Multiply both sides by 3 we have;

[tex]6 = x+3[/tex]

Subtract 3 from both sides we have;

3 = x

or

x = 3

therefore, the x-intercept of this line is, 3
