Every linear graph is just a straight line, so if there are any curves or unnatural shapes, than you know it is not linear. As for equations, if it can be shaped into y=mx+b where m and b are numbers, then it will be a linear equation.

Slope of 2 and passes through the point (-4,3). Write the equation in slope intercept form
erastova [34]

Answer:

The equation is y = 2x + 11.

Step-by-step explanation:

It is given that the gradient of the equation is 2. Using slope-form formula, y = mx+b where m is gradient and b is y-intercept. In order to find b, you have to substitute x-coordinate and y-coordinate into the equation :

y = mx + b

m = 2

At(-4,3),

3 = 2(-4) + b

b = 3 - 2(-4)

= 11

Stephanie can type around 70 words per minute. She has less than a week to type her final research paper. If the paper has to be
svetlana [45]
350*15 is 5250. That is the total words needed to reach her assignment paper goal. Since there are 60 minutes in an hour we would need to figure out how many words she can type per hour. 60*70 is 4200. Then we divide 5250 by 4200. We get 1.25. Soooo our final answer would be 1 hour and 15 minutes need to be set aside to type her assignment. I really hope this is correct it makes sense to me. If not i am truly sorry.

Let a = 10 ; and b = 2. With the given values, the equation below is true.
quester [9]

Answer:

The answer is:

\frac{2a}{2b}  = 5

Step-by-step explanation:

Substitute the values of a and b into the equation

a = 10&b = 2 \\ \\ \frac{2a}{2b}  = 5 \\ \\so \frac{2(10)}{2(2)}  = 5

\frac{20}{4}  = 5 \\ \\ 5 = 5
