Answer:

The y-intercept is about 25.385

Explanation:

Calculate slope from difference in y-values divided by difference in x-values.

-15/13 is slope.

Use slope-intercept form.

Y= mx + b

Substitute values from given coordinates for y and x, then solve for b

-60 = -15/13(74) + b

-60 = -85.385 + b

-60 +85.385 = b

25.385 = b
