Mr martin has 36 calculators in a box . the ratio of ordinary calculators to scientific is 5 : 1 how many of each calculator does he have ?me : )

First you add the ratio together like so: 5+1=6. Then, you divide 36 by that number: 36÷6=6
Now, use use this multiplier and times it by both ratios, so:
ordinary= 6×5=30
scientific= 6×1=6
There are 6 scientific calculators in the box

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!
