Answer:
The equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is
Step-by-step explanation:
Equation of line passing through the points (-7,25) and (-4,13) in slope-intercept form.
The general equation of slope-intercept form is:
First we need to find slope
The formula used for finding slope is:
We are given:
Putting values in formula and finding slope
So, slope m= -4
Now finding y-intercept
Using slope m=-4 and point (-7,25) we can find y-intercept
So, y-intercept b =-3
Now, the equation of required line having slope m=-4 and y-intercept b=-3 is:
So, the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is
We are given ratio 456:8.
The given ratio can be written in fraction form as
In order to find the rate, we need to divide 456 by 8, because it would give the unit value.
When we divide 456 by 8, we first take multiple of 8 closer to the number 45.
8*6=48 but it's greater than 45, so we would take 8*5 =40.
Subtracting 40 from 45, we get 5.
Getting 6 down, we get 56. Take multiple of 8 upto 56.
8*7= 56.
56 -56=0.
So, on dividing 456 by 8 we got 57.
Therefore, rate is 57 per unit.
