Select the correct answer from each drop-down menu.
Anettt [7]

y = -3/5(x-3)

y= (-3/5) x + 9/5

Step-by-step explanation:

Step 1 :

The equation of line in point and slope form is (y- y intercept) = m(x-x intercept)

Where m represents the slope and x1 and y1 are points on the line.

Given (-2,3) and (3,0) are points on the line

m = (y2-y1)/(x2-x1) = (0-3)/(3-(-2)) = -3/5

So the equation of the line in point slope form is

(y-0)= -3/5(x-3) = y = -3/5(x-3) [taking the point as (3,0)]

Step 2 :

The equation of a line in slope and intercept form is  y = m x +c

m denotes the slope and the constant c denotes the y intercept (the value of intercept in the y axis when x = 0)

when x = 0, y = 9/5 [using the equation in step 1]

Hence the equation in slope and intercept form is

y= (-3/5) x + 9/5

Steve had $140.50 dollars. He loaned $50 dollars to a friend, spent $31.25 dollars, and received his $80.75 dollars paycheck fro
Damm [24]

Answer:

Steve has a total of $140.

Step-by-step explanation:

At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.

140.50 - 50 = $90.50

So now, Steve has only $90.50 left.

Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.

90.50 - 31.25 = $59.25

Now, Steve has $59.25 left.

Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.

59.25 + 80.75 = $140

Therefore, Steve now has a total of $140.
