Question

Complete the point-slope equation of the line through (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis and (7,4)(7,4)left parenthesis, 7, comma, 4, right parenthesis.

Answer 1

Answer:

5y = x + 13

Step-by-step explanation:

(2,3) and (7,4)

Slope = (y2-y1)/(x2-x1)

= (4-3)/(7-2) = 1/5

y = (⅕)x + c

When x = 2, y = 3

3 = (⅕)(2) + c

c = 3 - ⅖

c = 13/5

y = (⅕)x + 13/5

Multiply the equation by 5

5y = x + 13

Answer 2
