Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?

The slope is -4

4

the slope is - 2 and the y intercept is 4

4

Slope equals (y2 - y1) / (x2 - x1). In this case, the points are (-2, -4) and (1, 2), so the slope is (2 - (-4)) / (1 - (-2)) = (2+4)/(1+2) = 6/3 = 2.

-2

2/3

2y = 8x - 3 divide by 2 to both sidesy = 4x - 3/2 (this is the slope-intercept form of the equation, where slope is 4)The slope is 4.

You have to re-arrange the equation to y=mx+b. X + 2y = 4 2y = -X +4 y= - 1/2 x + 2 your slope is X, so the slope = -1/2

slope of a line in standard form ax + by = c is -(a/b). So, your slope would be -(2/-4) or 1/2.

2x + 3y = 12 y = -2/3 y + 4 slope is -2/3
