y1 = 9 (2x-1) , y2 = 2x+1 and y1 is 276 more than 3 times y2

find all x values

Find all values of x satisfying the given conditions.

y1 = 7 - 7x, y2 = (4x + 9)(x - 1), and y1 - y2 = 0

i know you need to use the equation for finding the gradiant of aline in part (i), which would be:

(y2 - y1) / (x2 - x1)
substituing values: (7-3) / (-7-5) = 4/-12 = -1/3

so the gradient is y = -1/3x + c

the higher the number multiplied by x the steeper the gradient,however this is a small number which should give a less steepgradient.

My problem is how to find the 3rd point, part (ii). I know that youhave to use the equation for a straight line, y = -1/3x + c,however, when i find my 3rd point the line is quiet steep which itshouldnt be because every y value should be -1/3 of every xvalue
