Question

A line contains the points (4, 5) and (3,-9). Write the equation of the line using slope-intercept form. A. y=-2x - 3 B. y = 2x – 15 C. 1 yax +3 2 1 V= -X-7 2​

Answer 1

Y =-4X +21

Explanation:

x1 y1 x2 y2

4 5 3 9

(Y2-Y1) (9)-(5)= 4 ΔY 4

(X2-X1) (3)-(4)= -1 ΔX -1

slope= -4

B= 21

Y =-4X +21
