Answer:

[tex]y-2=-\frac{3}{4} (x-7)[/tex]

Step-by-step explanation:

Pre-Solving

We are given that a line passes through (7, 2) and (3, 5). We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.

First, we need to find the slope.

Solving

Slope

We need to find the slope (m) of the line.

We can use the following formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points.

Though we already have the values of the points, we can label the values of the points to avoid confusion and mistakes.

[tex]x_1=7\\y_1=2\\x_2=3\\y_2=5[/tex]

Now, substitute into the equation.

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{5-2}{3-7}[/tex]

[tex]m = -\frac{3}{4}[/tex]

Equation

Substitute [tex]-\frac{3}{4}[/tex] as m in [tex]y-y_1=m(x-x_1)[/tex].

We get:

[tex]y-y_1=-\frac{3}{4} (x-x_1)[/tex]

Now, substitute 7 as [tex]x_1[/tex] and 2 as [tex]y_1[/tex].

We get:

[tex]y-2=-\frac{3}{4} (x-7)[/tex]
