To get the equation of a line, you can use the following:
y - y1 = m (x - x1)
Where:
- m is the slope (2)
- y1 is the y coordinate of a point (1, -5)
- x1 is the x coordinate of the same point (1, -5)
Just substitute in the values:
y - y1 = m (x - x1)
y - (-5) = 2(x - 1) <em>( - - 5 = + 5 )</em>
y + 5 = 2(x - 1)

Answer:
B. y + 5 = 2(x - 1)
Answer:
8 hours
Step-by-step explanation:
1. Subtract value of tips she got that day
87.05 - 50.25 = 36.8
36.8 is the actual payment for her job that day
2. Divide 36.8 with paid/hour (4.6)
36.8 ÷ 4.6 = 8 hours
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
Answer:
B.
Step-by-step explanation:
8/7 - 5x + 2 = x/5 - 12
8/7 + 14 = x/5 + 5x
106/7 = 26x/5
x = 265/91
