Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]

To find the equation's y-intercepts, you can rearrange the variables, and isolate/get y by itself

#1

cx + ay = b     Subtract cx on both sides

ay = b - cx        Divide a on both sides

y=\frac{b}{a}-\frac{c}{a}x    (0, \frac{b}{a}) is your answer

Do the same for the rest, and you should get:

#2 (0, \frac{a}{b})

#3 (0, \frac{c}{b})

#4 (0, \frac{c}{a})

8 A video game that usually costs $50 is on sale for $32.50
finlep [7]

The video game is on 35% discount.

Step-by-step explanation:

Cost of video game = $50

Price on sale = $32.50

Amount of discount = Original price - price on sale

Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5

Percentage = \frac{Dicount\ Price}{Original\ Price}*100

Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%

The video game is on 35% discount.
