Your slope is wrong! Your slope is going to be 3/2, or C for the first problem. Your y intercept is wrong! Your Y- intercept is actually (0, -1.3) or B for the second problem.
Your equation is going to be
y= 3/2x-1.3
Answer:
12.5pages
Step-by-step explanation:
50pages ×6hours=300 and then we divide by 8 to get 37.5(the number of pages printed by david in 6 hours)
subtract 37.5 from 50 to find the number of pages printed by andy
Answer:
135
Step-by-step explanation:
I am not sure if you have to use the substitution method but I just did (600 - 60) then divided by 4
You add all of it up and divide by how many numbers are.... so the answer would be D- 56
- Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept.
If two lines are perpendicular, then they will have slopes that are <u>negative reciprocals</u> to each other. An example of negative reciprocals are 2 and -1/2

Now with line 2, I have to convert it to slope intercept form. Firstly, subtract 2x on both sides of the equation: 
Next, divide both sides by -5 and your slope-intercept form is 
Now since 2/5 is <em>not</em> the negative reciprocal of -2/5, <u>these lines are not perpendicular.</u>

It's pretty much the same process; convert to slope-intercept and determine if negative reciprocal. This time I'll brush through them:

Now since 2 <em>is</em> the negative reciprocal of -1/2, <u>these lines are perpendicular.</u>
