Answer:
Step-by-step explanation:
eq of a line through (x1,y1) and slope m is
y-y1=m(x-x11)
y+3=3(x+4)
y+3=3x+12
y=3x+12-3
y=3x+9
Answer:7
Step-by-step explanation:
just because
Answer:
<em>y = 3x + 1</em>
Step-by-step explanation:
y = mx + b
The slope, or <em>m</em>, is 3.
The y-intercept, or <em>y</em>, is 1.
Plug them into the equation.
y = mx + b
<em>y = 3x + 1</em>
Answer:
b
Step-by-step explanation:
Supplementary angles: sum of the angles measure to be 180º
180º-A= B
Plug in...
180º-80º= 100º
So, angle B must be 100 degrees.
