Answer:
y = 2x + 5
Step-by-step explanation:
First find the slope:
5-7/0-1 --> -2/-1 --> (2)
Now use the point-slope form to find the slope-intercept form:
y-7 = 2 ( x - 1)
y - 7 = 2x - 2 add seven to both sides...
y = 2x + 5
Answer:
10 : 30
Step-by-step explanation:
Subtract 5x from both sides, 7x+2=-26, subtract 2 from both sides, 7x=-28, divide both sides by 7, x=-4
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35
Divide
C=-5
