Can some one help me.

Answer:

The slope is 3

Step-by-step explanation:

m = rise/run

m = (y2 - y1)/(x2-x1)

points: (0,-5), (1,-2)

m = ((-5) - (-2))/ ((0) - (1))

m = (-5 + 2)/ (-1)

m = -3/-1

m = 3

2. Sketch the graph: 4y – 3x = 12.

goblinko [34]

Answer:

see below

Step-by-step explanation:

A graphing calculator is useful for this.

To find the x-intercept, set y=0 and solve for x:

0 -3x = 12

x = -4 . . . . . . divide by -3

To find the y-intercept, set x=0 and solve for y:

4y - 0 = 12

y = 3 . . . . . . divide by 4

Plot the x- and y-intercepts on their respective axes and draw a line through them.
