HELP What is the slope of a line with the equation 3x+7?

m=3

Step-by-step explanation:

The equation of the line is in slope-intercept form, or:

y=mx+b

where m is the slope and b is the y-intercept. The slope is multiplied by x and the y-intercept is added or subtracted from that.

The equation of the line is:

y=3x+7

3 and x are being multiplied, therefore 3 is the slope. 7 is added to 3x, therefore 7 is the y-intercept.

The slope is 3, or 3/1. Therefore, on a graph, the line will rise 3 up, then run 1 to the right.

The slope of the line is 3.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
