Work out m and c for the line: y = 4 x − 1

Mathematics

Answer:

m=4 and c=-1

Step-by-step explanation:

I'm assuming that m is the slope and c is the y-intercept. (If this is not the case, please tell me and I'll fix my answer).

The equation is already in the form y=mx+c so you just take the numbers from the problem y=4x-1.

Answer:

m = 4    c=-1

Step-by-step explanation:

The slope form is y = mx + b.

M is the slope which is 4.

B is the y=intercept which is -1.

What is the slope of the line represented by the equation 10x - y = 2?
matrenka [14]

Answer:

D. 10

Step-by-step explanation:

To find the slope of the equation, we first need to put the equation into slope-intercept form:

y=mx+b

So first, we need to get y by itself.

10x-y=2

Subtract 10x from both sides.

-y=-10x+2

Then, divide -1 on both sides.

y=10x-2

Slope=10

The sum of two numbers is 52 . The smaller number is 16 less than the larger number.What are the numbers?
eimsori [14]

Answer:

This question is not as hard as it seems.

Let the first number = x.

The other number will be x - 16.

The sum of both the number is 52.

So, x+x-16 = 52

Which would simplify to 2x -16 = 52.

When I add 16 to both sides, it would give me 2x = 68.

Then, divide both sides by 2.

This leaves us with x = 34.

Since we have x, now x-16 would be 34-16 = 18.

The two numbers are 34 and 18, this answer is correct because both of them add up to give me 52.

HOPE THIS HELPS!
