There is a line that includes the point(10, 5)and has a slope of 1 What
ziro4ka [17]

Answer:

y = x - 5

Step-by-step explanation:

Given the point, (10, 5), and the slope, m = 1:

Substitute these values into the <u>slope-intercept form</u> to solve for the y-intercept, <em>b</em>:

y = mx + b

5 = 1(10) + b

5 = 10 + b

Subtract 10 from both sides to isolate b:

5 - 10 = 10 - 10 + b

-5 = b

The y-intercept of the line is: b = -5. This represents the y-coordinate of the y-intercept, (0, -5), which represents the point on the graph where it crosses the y-axis. Along the y-axis, the value of x = 0. Hence, the y-intercept is (0, -5).  

Therefore, given the slope, m = 1, and the y-intercept, b = -5:

The equation of the line in slope-intercept form is:  y = x - 5.

The formula in finding the area of a circle can be derived usin the perimeter of a rectangle
Alex777 [14]

Yes absolutely as if you just take a circle and break the circle from the centre point into pieces such that the no

of pieces formed is infinite and and then when you take the pieces of the circle and arrange them in the form of rectangle then the area of the rectangle obviously equal to the area of circles.For better understanding I had attached a picture with the answer

Hope it helps
