Answer:
X=-1, y=1
Step-by-step explanation:
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
Point slope uses one point and the slope. We’ll use (4,10)
Y - 10 = 2 • (x - 4)
But it can also be
Y - 4 = 2 • (x - 1)
Whichever you prefer to use
Using the Pythagorean theorem we can solve for the missing leg.
The equation is a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.
Filling in a and c with the information provided we will solve for b ( the missing leg).
1^2 + b^2 = 3^2
1 + b^2 = 9
b^2 = 9-1
b^2 = 8
b = SQRT(8)
b = 2 SQRT(2)
Exterior Angle property = sum of interior opposite angle is equal to the exterior Angle
x= 48+96
x= 144°
The slope intercept form is y=-x-5
