-8x = 30 - 10y

you want to solve for y
add 10 y to both sides
10y-8x=30
add 8x to both sides
10y=8x+30
divide both sides by 10
y=4/5x+3
y intercept is 3, slope is 4/5

Add 10 y to both sides to get
10y-8x=30
Now add 8x to both sides and you have
10y = 8x + 30
Divide both sides by 10 and you have
y = 8/10x + 3
This is the general y = mx + b format for the equation, where m represents the slope and b represents the intercept, so the slope is 8/10 and the intercept is 3.

Step 1. Divide each term by 2.
Step 2. Rearrange the answer into slope-intercept form (y = mx + b).
Step 3. Divide each term by the coefficient of y (the number still attached to y). The number attached to the x is the slope, and the last term is the y-intercept.

The Y-Intercept is 3 and the slope is 0.8
