Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
Answer:
1. 135°
2. 62°
3. 148°
4. 180-x
Step-by-step explanation:
Supplementary angles are two angles that add to 180 degrees (a straight line).
Therefore, subtract the angle measure they give you from 180.
Hope this helps!
Answer: 
Step-by-step explanation:
You can use the Method of substitution.
Substitute the equation 
into the equation 
and then you must solve for the variable x:
Apply Distributive property:
Subtract 12 from both sides of the equation and then add the like terms. Then you get:
