Answer:
y = 3/4x - 13
Step-by-step explanation:
As we already know the slope, we just need to find the y-intercept.
y = 3/4x +b
-7 = 3/4(8) + b
-7 = 6 + b
-13 = b
90 degrees
360/4=90
In disguise right arrow In Standard Form a, b and c
x2 = 3x − 1 Move all terms to left hand side x2 − 3x + 1 = 0 a=1, b=−3, c=1
2(w2 − 2w) = 5 Expand (undo the brackets),
and move 5 to left 2w2 − 4w − 5 = 0 a=2, b=−4, c=−5
z(z−1) = 3 Expand, and move 3 to left z2 − z − 3 = 0 a=1, b=−1, c=−3

Expand both factors and collect like term
Using Pascal' triangle with n = 6 to obtain the coefficients

Decreasing powers of 1 from to
Increasing powers of 3x from to
= 1. + 6. + 15. + 20. + 15.1² + 6. + 1.
= 1 + 18x + 135x² + 540x³ + 1215 + 1458 + 729
--------------------------------------------------------------------------------------
= 1 - 18x + 135x² - 540x³ + 1215 - 1458 + 729
----------------------------------------------------------------------------------
Collecting like terms from both expressions
+
= 2 + 270x² + 2430 + 1458

Increasing powers of 2x from to
= 1. + 5. + 10. + 10. + 5.+ 1.
