The graph of a linear function passes through the point (-1, 2) and has a slope of 3. What is the equation of the function in sl
Harman [31]

Answer:

The equation of the function in slope-intercept form is y = 3 x + 5 .

Step-by-step explanation:

Given as :

A line passes through the point ( - 1 , 2 )

i.e ( x , y ) = ( - 1 , 2 )

The slope of the line is 3

The equation of line in slope intercept form

y - \textrm y_1 = m ( x - \textrm x_1 )

Where m is the slope of the line

So, y - 2 = 3 ( x - ( - 1 ) )

Or, y - 2 = 3 ( x + 1 )

Or, y - 2 = 3 x + 3

Or, y = 3 x + 3 + 2

∴   y = 3 x + 5

Hence The equation of the function in slope-intercept form is y = 3 x + 5 . Answer

Please help with explaition <br>​
VMariaS [17]

Answer:

1/20

Step-by-step explanation:

The probability of any of the friends sitting on any of the seats is equal.

So the probability of Hamad sitting on the first seat = 1/5

As Hamad is sat on the first seat, there are now 4 available seats, so the probability of Riyadh sitting on the second seat = 1/4

Therefore, probability of Hamad sitting on the first seat AND Riyadh sitting on the second seat = 1/5 x 1/4 = 1/20
