Answer:
x = 19
Step-by-step explanation:
By the Supplementary Angle Theorem we can say that;
123 + 3x = 180
3x = 57
x = 19
Hope this helps!
Answer:
y=-1/4x+19/4
Step-by-step explanation:
I hope this helps
The equation you were supposed to use is
y=mx+b
b= Y-intercept
m= slope
In this case the slope is -1/4
The Y-inetcept is 19/4
Three points in a plane may not necessarily form a triangle. Let's say three points have the same x-value but different y-values. Then these points will form a line segment rather than a triangle
Hope this helps
y+1=3(x-4)
Multiply the bracket by 3
y+1=3x-12
Follow y=mx+b Move +1 to the other side. Sign changes from +1 to -1
y+1-1=3x-12-1
y=3x-13
Slope=m = 3
b= y-intercept=-13
Answer: Slope=m=3- D.
