For what value(s) of k will the relation not be a function? 1.B={(k^2-5k,10),(k+7,4)}
2.R={(k^3-5k^2+3k,-5),(-k,4)}
3.S={(|k+1|+2,4),(8,7)}
Solving any helps, but if you can solve all of them I would be so grateful and I will mark brainliest.

Find the area of a trapezoid with a height of 23, base 1 of 10 and base 2 of 18

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Plzzzz i beg u asap ! what is the equation of this graphed line? enter your answer in slope-intercept form in the box.
