Write an equation of a line with the given slope and y-intercept. m = –2, b = 4

Step-by-step explanation:

The given data is

Where is the slope of the line and is the y-intercept. So, basically this line has a slope of -2 and y-intercept at 4.

To find its equation, we use the slope-interception form

Then, we replace each given value

Therefore, the equation for the given line is

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
