Find the slope of the line whose equation is 7x-2y=4

borishaifa [10]

Answer:

$\huge\boxed{\text{Slope: } \frac{7}{2}}$

Step-by-step explanation:

In order to find the slope of this equation, we can convert it into slope-intercept form, where we can find the slope more easily.

Slope intercept form is usually in the form $y=mx+b$ , where m is the slope and b is the y-intercept.

Let's algebraically manipulate this problem so we solve for y.

$7x - 2y = 4$
$-2y = 4 - 7x$ (Subtract 7x from both sides)
$y = -2 + \frac{7}{2}x$ (Divide both sides by -2)
$y = \frac{7}{2}x-2$ (Rearrange the equation)

From here, we can now see our equation is $y = \frac{7}{2}x-2$ , in the form $y=mx+b$ . Since m is the slope, and $\frac{7}{2}$ is m, our slope is $\frac{7}{2}$ .

Hope this helped!

Sam is driving home from college. He is 220 miles away from home. If he can make it home in 4 hours, at what speed or velocity i

yan [13]

Answer: 55 miles per hour

Explanation: that hint is really useful
So if distance = velocity x time
That means 220 = v x 4 hours
To find v, divided 220 by 4
220 divided by 4 = 55
But I have a question:
Is he driving at a constant speed?
and is this 6th grade math? I’m in that grade but you can trust my answer
If im wrong, someone pls correct me
If im right, mark me brainliest pls, im broke, i have no points-
Goodluck!
