Answer:
y = - 2x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (1, 7) into the partial equation
7 = - 2 + c ⇒ c = 7 + 2 = 9
y = - 2x + 9 ← equation of line
Answer:
Step-by-step explanation:
To be perpendicular the product of the two slopes is equal to negative one.
m1(m2)=-1, in this case the slope of the reference line is 1/3 so the other line will have a slope
m/3=-1
m=-3 so our perpendicular line is
y=-3x+b, using point (3,-5) we can solve for the y intercept b
-5=-3(3)+b
-5=-9+b
b=4 so the completed perpendicular line passing through point (3,-5) is
y=-3x+4

PEMDAS
Multiplication:
10* -4 / 3*9 = -40 / 27
Addition:
-40 / 27 + 7/6 find common denominator 108
-40*4 / 27*4 + 7*18 / 6*18
-160 / 108 + 126 / 108
-34 / 108
-17 / 54
Subtract:
-17 / 54 - 2/5 common denominator 270
17*5 / 54*5 - 2*54 / 5*54
-85 / 270 - 108 / 270
-193 / 270
-193/ 270 = -0.7148
-8 / 15 = -0.7148 :)
