Answer:

y- intercept = 5

Step-by-step explanation:

to find the y- intercept let x = 0 in the equation and solve for y

this relies on the fact that when the line crosses the y- axis the x- coordinate is zero, then

0 - 2y = - 10 , that is

- 2y = - 10 ( divide both sides by - 2 )

y = 5

then y- intercept = 5

What steps do you use to solve y=x+12 and y=-x+17 an unknown number y is 12 more than an u known number x the number y is also x
Tamiku [17]

Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

x+12=17-x

Add x to both sides to remove the negative x on the right side of the equation:

2x+12=17

Subtract 12 from both sides to remove the 12 on the left side of the equation:

2x=5

Divide both sides by 2 to cancel out the x coefficient

x=2.5
