Answer:
y +2 = 4/5(x -2)
Step-by-step explanation:
The two marked points differ vertically by 4 (rise = 4) and horizontally by 5 (run = 5). The slope is ...
m = rise/run = 4/5
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For slope 4/5 and point (2, -2), the equation is ...
y +2 = 4/5(x -2)
Answer:
C. (-7, -15)
Step-by-step explanation:
Both the x- and the y-coordinates of a point in the third quadrant are negative. The given point C. (-7, -15) is the only one of the four choices that satisfies this criterion.
