Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4
Answer:
the slope is 
Step-by-step explanation:
Notice that you are given two points to use for the slope calculation:
So we use the formula for the slope of a line given two points:
Answer:
Step-by-step explanation:
the sum of the angles in a triangle is 180
33+2c+c-18=180
3c=180+18-33
3c=165
c=165/3
c=55
It would be the last graph because at the x-intercept, it crosses the 5
