What is the equation of a line that passes through (1, 3) and has a slope of 2?

Y=mx+b m=slope b=y intercept y=2x+b subsitute point (x,y) (1,3) x=1 y=3 subsitute 3=2(1)+b 3=2+b subtract 2 1=b equation y=2x+1

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!

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
