A line passes through the point (10,9) and has a slope of 3/2. Write an equation in slope intercept form for this line
Andre45 [30]

Answer:

The equation of line passing through (10,9) and having slope 3/2 is: y = \frac{3}{2}x-6

Step-by-step explanation:

The slope intercept form of a line is given by:

y=mx+b

We are given

Slope = m = 3/2

Point = (10,9)

Putting the value of the slope in the equation we get

y = \frac{3}{2}x+b

b is the y-intercept. To find the y-intercept we have to put the point through which the line passes in the equation.

Putting (10,9) in the equation

9 = \frac{3}{2}(10) +b\\9 = 15+b\\b = 9-15\\b = -6

Putting b=-6 in the equation

y = \frac{3}{2}x-6

Hence,

The equation of line passing through (10,9) and having slope 3/2 is: y = \frac{3}{2}x-6

Twice a certain number is tripled. The resulting number is​
Alekssandra [29.7K]

Answer:

6x the number.

Step-by-step explanation:

"Twice a certain number" means that you are multiplying that number (x) by 2.

"Tripled" means that the number (x) would be further multiplied by 3.

Simplify: 3 x 2 = 6

The resulting number would be 6x greater than the original number.
