Answer:

Point-Slope form:

The equation of line is given by:

y-y_1 = m(x-x_1)

where,

m is the slope of the line and (x_1, y_1) is the point on the line.

As per the statement:

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

Using slope formula:

\text{Slope(m)} = \frac{y_2-y_1}{x_2-x_1}

then;

m = \frac{2-(-4)}{6-(-3)}=\frac{6}{9} = \frac{2}{3}

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

y-(-4) = \frac{2}{3}(x-(-3))

⇒y+4 = \frac{2}{3}(x+3)

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

x-intercept:

Substitute y =0 and solve for x:

then;

0+4 = \frac{2}{3}(x+3)

⇒4 = \frac{2}{3}(x+3)

⇒2 = \frac{1}{3}(x+3)

Multiply both sides by 3 we have;

6 = x+3

Subtract 3 from both sides we have;

3 = x

or

x = 3

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