What is the equation of a line with a slope of 4 and a y-intercept of 2?
grandymaker [24]

Slope-intercept form:  y = mx + b  [m is the slope, b is the y-intercept or the y value when x = 0 -->  (0, y)  or the point where the line crosses through the y-axis]

Since you know:

slope(m) = 4

y-intercept(b) = 2           Plug it into the equation

y = mx + b

y = 4x + 2

Blakes goes from averaging 8 hours of sleep for a school night to averaging 6.5 hours of sleep on the weekend. What is the perce
beks73 [17]

Answer:

Step-by-step explanation:

So Blakes sleep 8 hours per night during the school day

8 hours/night...................................100%

6.5 hours/night...................................?

6.5*100/8=81.25

the change in percentage is 100-81.25=18.75%

the percentage change is 18.75

if it is easier for you, another method is:

8-6.5=1.5 subtract the original amount to the new amount

1.5/8=0.1875 divide by the original amount

0.1875*100=18.75 find the percentage
