1. A line that passes through the point (-1, 3) has a slope of 2. Find another point on the line. O A. (0,5)
O B. (1,5)
O C. (1.4)
OD. (-3, 2)

option Bis correct answer.

Step-by-step explanation:

given, a line passes through the point (_1,3)and has slope 2.let another point be x2 and y2.

by the slope formula,

slope (m)=

or , 2=y2_3/x2_(_1)

or, equating with slope we get,

2=y2_3

or, y2=5

again, 2=x2+1

therefore, x2=1

so the points are (1,5)........ans....

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
