write the equation of the line in slope intercept form with the given conditions (slope = 3 and passes through (1,-3))

cupoosta [38]

Answer:

Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)

Step-by-step explanation:

m=3 , x1=1 , y=-3

y-(-3)=3(x-1)

y+3=3x-3 subtract 3 from both sides

y=3x-6 the answer in the slope-intercept form y=mx+b

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-8, -1)

Point (-3, 9)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(-3+8)^2+(9+1)^2}$
Add: $\displaystyle d = \sqrt{(5)^2+(10)^2}$
Exponents: $\displaystyle d = \sqrt{25+100}$
Add: $\displaystyle d = \sqrt{125}$
Simplify: $\displaystyle d = 5\sqrt{5}$
Evaluate: $\displaystyle d = 11.1803$
Round: $\displaystyle d = 11.2$

Bernie got 12 out of 20 math problems correct on his test. What percentage did he get correct?

DaniilM [7]

Answer:

60%

Step-by-step explanation:

$\frac{12}{20}$ × $\frac{100}{1}$ = 60%

You put 12 over 20 and multiply it by 100 over 1 and you cancel and multiply to find your answer.

(when you are trying to find the percentage you multiply by 100)
