Answer:
if ur trying finding the y-intercept it's -24
Step-by-step explanation:
slope- intercept form is y=mx+b we know m is 4 (7,4) 7 is the x 4 is the y ...
then you plug them in and we know 4 times 7 is 28 and then 4-s8 is -24
Step-by-step explanation:
You should always use the least number of significant figures. The exception is exact numbers or constants.
For example, there are 60 minutes in an hour. Even though this number has one significant figure, it is an exact number. So 15 minutes converted to hours would be 0.25 hr.

Answer:
AB and CD are parallel lines
Step-by-step explanation:
• Parallel lines have equal slopes
• The slopes of perpendicular lines are negative reciprocals
Calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
let (x₁, y₁ ) = A(1, 4) and (x₂, y₂ ) = B(3, 8)
m =
=
= 2
let (x₁, y₁ ) = C(- 1, 6) and (x₂, y₂ ) = D(3, 14)
m =
=
= 2
Since slope of AB and CD are equal then lines are parallel
Given a temperature C in celsius, you can convert it to Fahrenheit by using the formula

In your case C=39, so you have
