the equation for line p can be written as y= -9x +5. line q is perpendicular to line p and passes through (-9, 2). what is the equation of line q?​

y=mx+b where m is the slope and b is the y intercept

y=-9x+5 so the slope is -9 for lines to be perpendicular

m1(m2)=-1 so the line q will have a slope -9m=-1, m=1/9 so

q=x/9+b, using point (-9,2) we can solve for b

2=-9/9+b

2=-1+b

b=3 so

q=x/9+3, or more neatly

q=(x+27)/9

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
