Please help! What is the line's slope??

1 answer:

4 0

The slope is the rise over run. Basically, any line has a constant increase. If you are looking at a line on a graph and each point it meets at is 1 up and 1 over, the slope is 1. Say the line goes up two and over one for each time it meets an actual point, the slope would be 2. If it is 1 up and 2 over, it would be 1/2.

Step-by-step explanation:

Step 1:

Let the number be 50 and to find 40% of 50 is given interms of expression as follows

To express the percentage the following strategy is used

Eg: 40% = $40/100$

∴ To express 40% of 50 is

$(40/100)*50$

Step 2:

On simplification the above expression we could get

$0.4*50$

= 20

A line has a slope of 8 and a y-intercept of 0 what is its equation in slope intercept form

Deffense [45]

Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.

1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x

2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2

The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.

Hope this helps!
