Accepted Solution

A:
Answer:See attachedStep-by-step explanation:When there is a lot of repetitive calculation to do, I like to let a spreadsheet or graphing calculator do it. The attached shows a spreadsheet that computes all the values you're asked to find.For a linear equation in standard form, ax +by = cthe x-intercept is: c/athe y-intercept is: c/bthe slope is: m = -a/bOf course, the slope-intercept form of the equation is ... Β  y = (slope)Β·x + (y-intercept)and the values of the various points on the graph can be computed from that equation.___You will note that the last two equations describe the same line._____Note on spreadsheet formulasWhen you put the formulas into the spreadsheet, make sure to fix the column number or row number of the values you're computing, as appropriate. For example, the y-values in the different columns always use the slope from the slope column (fixed), the y-intercept from that column (fixed), and the x-value from the top row (fixed). If you make the cell references relative instead of fixed, you will get wrong answers.
