Apatient received only 3/4 of the 20mg. does of medication he was supposed to get. how many milligrams of the medication did he received?

Multiply fraction by the total amount of medicine

=3/4 * 20 mg
multiply numerator by 20
=(3*20)/4
=60/4
=15 mg

ANSWER: He received 15 mg of medicine

Hope this helps! :)

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!
