Which is the equation of a line that has a slope of -2/3 and passes through point (3, 1)?

Y = (2/3)X + 1
Y = (2/3)X + 3
Y = (-2/3)X - 1
Y = (-2/3)X - 3

Final answer:

The equation of a line with a slope of -2/3 that passes through the point (3, 1) is y = (-2/3)x + 3 by substituting the point into the slope-intercept formula and solving for the y-intercept.

Step-by-step explanation:

The question asks for the equation of a line with a slope of -2/3 that passes through the point (3, 1). The formula for the equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Since the slope is given, we only need to solve for b by using the coordinates of the given point:

y = mx + b

1 = (-2/3)(3) + b

1 = -2 + b

b = 1 + 2

b = 3

Therefore, by substituting the slope and the calculated y-intercept into the equation, the equation of the line is:

y = (-2/3)x + 3
