Answer:

The y-intercept is about 25.385

Step-by-step 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

Write an equation os the line that passes through the givin points (-2,7) (3,-3)

ryzh [129]

(-2,7)(3,-3)
slope(m) = (-3-7) / (3 - (-2) = -10/(3 + 2) = -10/5 = -2

y = mx + b
slope(m) = -2
use either of ur points (-2,7)...x = -2 and y = 7
now sub and find b, the y int
7 = -2(-2) + b
7 = 4 + b
7 - 4 = b
3 = b

so ur equation is : y = -2x + 3 or 2x + y = 3
