Answer:
• General equation of a line:
- m is the slope, m = 2/5
- b is y-intercept
• Therefore, equation of line is:
Answer:
1..25a
Step-by-step explanation:
a + 25%·a = a(1 + 0.25) = 1.25a

<em>Comment on percentages</em>
The symbol "%" is a shorthand way to write "/100", so 25% = 25/100 = 0.25.
Of course, 100/100 = 100% = 1.
Adding 25% of something to 100% of it gives 125% of it, the original amount multiplied by 125/100 = 1.25.

-3+16
= 13
Answer:
y = -1/2x - 2
Step-by-step explanation:
The line is negative, so the slope has to be negative. (-1/2)
You would use the equation to find the first point to plot. -1/2 times 0 is 0. 0-2 equals -2. This means that the first point would be (0,-2). This proves that the correct equation is <u><em>y = -1/2x - 2</em></u>.
