Answer:
y = x + 1
Step-by-step explanation:
Since slope is 1, then the equation will be formatted as y = x+b, since m is 1. Now we need to solve for b, since we're given a coordinate that is on the line, replace x and y for these two points to solve for b.
y = x + b (subsitute)
-1 = -2 + b (add 2 to both sides)
1 = b
So your final equation is y = x + 1.
Answer:
multiply the numerators; express that product over the product of the denominators
Step-by-step explanation:
Multiplication of fractions is done the same way regardless of whether the denominators are the same or different.
The numerator of the product is the product of the numerators.
The denominator of the product is the product of the denominators.
Cross multiply to see if they both have the same product

Answer:
-5
Step-by-step explanation:
- 9(2x+15)=45
- 18x+135=45
- 18x=45-135
- 18x=-90
- x=-90/18
- x=-5
