The easiest method to find the slope and y-intercept is to convert this standard form equation to slope-intercept form. Firstly, subtract 8x on both sides of the equation:
Next, divide both sides by 12, and your slope-intercept form is:
Now looking at this slope-intercept form, we can see that the <u>slope is -2/3 and the y-intercept is (0, 3/4).</u>
Answer:
José has 49 used stamps
Step-by-step explanation:
7 used stamps for every 4 new stamps
To solve this type of problem, we can use a ratio
7 : 4 ratio
He has 28 new stamps
7 : 4 = x : 28
Ratios can be written as fractions
Cross multiply
4x = 7(28) = 196
Divide by 4 on both sides
x = 49
Hope this helps :)
