What is the slope intercept form of an equation that goes through (-3,-5) and slope is 3/7
svet-max [94.6K]

Answer:

Step-by-step explanation:

Point slope form: y−7=34(x−3)

Slope intercept form: y=34x+194..or..y=34x+434

Explanation:

Since you have one point and the slope, you can use the point slope formula, then solve for y to get the slope intercept form, so that you can determine the y-intercept (b). Then you can graph the resulting equation.

Point slope formula

y−y1=m(x−x1), where x1,y1=(3,7), and m=34 is the slope.

Substitute the given values into the formula.

A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose 1/10 degree every 1/4 hour for
klio [65]

Answer:

The rate is \frac{2}{5} degree per hour.

Step-by-step explanation:

Given : A scientist conducted an experiment. Due to chemical reaction, the temperature of a compound rose \frac{1}{10} degree every \frac{1}{4} hour for a limited time.

To find : What was the rate, in degrees per hour that the temperature of the compound rose ?

Solution :

In every \frac{1}{4} hour the temperature of a compound rose \frac{1}{10} degree

To get  the rate, in degrees per hour,

In every 1 hour the temperature of a compound rose is

r=\dfrac{\frac{1}{10}}{\frac{1}{4}} degree

r=\dfrac{4}{10} degree/hr

r=\dfrac{2}{5} degree/hr

Therefore, the rate is \frac{2}{5} degree per hour.
