Answer:
x = 30°
Step-by-step explanation:
We know that the sum of all of the interior angles of a triangle is 180°, therefore, we can write the following equation:
x + 2x + 3x = 180
6x = 180
x = 30°
I'm pretty sure it's 737+w
Answer:
y=2x-4
Step-by-step explanation:
find the gradient
m=y2-y1/x2-x1
m=2-0/3-2
m=2
then find the equation
y-y1=m(x-x1)
y-0=2(x-2)
y-0=2x-4
y=2x-4
Answer:
y=3x-8
Step-by-step explanation:
find the slope by using the slope formula: y2-y1/x2-x1 so 4-1/4-3 solve 3/1 so the slope is 3. standard lines are y = mx+b plug it in with one of the points: 4= 4(3) + b the m is the slope and I plugged the x and y points 4 into it. 4=12+b subtract 12, b=-8 that is the y intercept.
check 1=3(3) + b, 1= 9 + b, -8= b:
so the y intercept is -8 the slope is 3 now we replace it to get a linear equation;
y=3x-8
