The formula gives the height h = a/b of a parallelogram with area a and base b.
what is the height of a parallelogram with an area of 78 cm2 and a base of 13 cm?

Just substitute in the formula 78 = h x 13 78/13 =h 6= h

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!
