Answer:

$y=-\frac{3}{4} x-4$

Step-by-step explanation:

When writing an equation of a line using slope-intercept form: y=mx+b, the slope of the line would take the place of m, and the y-intercept would take the place of b. Just substitute these variables for the slope and y-intercept to find the equation of the line.

lmk if this is incorrect, hope it helps!!

Answer:

y= -3/4x-4

Step-by-step explanation:

This is assuming that you want it in slope-intercept (y=mx+b)

You need to know that

Y= The line

m=Slope

b=y-intercept

Step 1, Replace slope (m)

y= -3/4x+b

Step 2, Replace the y-intercept

y= -3/4x-4

Conclusion to 'what is the equation of the line if its slope is -3/4 and Y-intercept is -4': y= -3/4x-4

If x varies directly as y, then what is y when x = 4, knowing that x = 60 when y = 5?

Answer: The answer would be 1/2

Step-by-step explanation:

Y varies DIRECTLY as x. Find the constant of variation, k, if y = -5x

The first sentence is there for information, the constant is a number( 1,2,3...so on) , so the only number is -5

It is a linear equation meaning equation of a straight line.

its form is y= mx+b, where m is the slope of the line, b is the y intercept when x=0. these info you have to memorize like your life depend on it.

next, y varies directly as x. If y = 15 when x = 60, find y when x = 100

if y= 15, when x=60, then there is a number m such that m*y= 60

or m= 60/y= 60/15 =4

so the equation is y=4x. in this cause, the b=0

so when x=0, y=0

The distance a car travels at a constant speed varies directly as the time the car spends traveling. If a car traveled 105 miles in 3 hours, how far could the car travel in 5 hours?

remember that distance = speed times time.

or d=Vt

so car goes 105 miles on 3 hours

how far it goes in one hour?

if you know that, then you can tell how far it goes in 5 hours.
