Aparticular sheet of paper measures 8.5 × 6.5 inches. what is the surface area of one side of the paper in cm2? (2.54 cm

The surface area of the square on one side is simply the product of its length and width dimensions. Notice that the given data is in inches while the area asked should be in centimeters. To maintain consistency of units, convert inches to cm first using the conversion 1 in = 2.54 cm

8.5 in * 2.54 cm/in = 21.59 cm
6.5 in * 2.54 cm/in = 16.51 cm

Area = (21.59 cm)(16.51 cm)
Area = 356.45 cm²

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
