Answer:

The slope of the line is 4.

The Y intercept of the line is -6.

Step-by-step explanation:

The slope intercept form of a line is

y=mx+b           .... (1)

where, m is slope and b is y-intercept.

The given equation of line is

y=4x-6             .... (2)

On comparing (1) and (2) we get

m=4

b=-6

It means the slope of the line is 4 , The Y intercept of the line is -6. the graph of a linear function is a straight line.

The value of y is -6 at x=0, so the line do not passes through the origin.

Therefore, the correct statements are "the slope of the line is 4  and the Y intercept of the line is -6".

Find the area of the figure.
seraphim [82]

Answer:

10 x 15 = 150

Area of trapezoid:

10 + 20 = 30

30 x 5 = 150

20 - 15 = 5

150 divided by 2 ( x 1/2) = 75

75 + 150 = 225 square cm

Formula of a trapezoid:

B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)
