Answer:

The value of b is 2  and The equation of line is y = 3 x + 2 .  

Step-by-step explanation:

Given as :

The slope of line is 3

The points through which line passes is ( x , y ) = ( 1 , 5 )

Now,

The equation of line in slope-intercept form

y = m x + c

Where x and y are the points on axis

m is the slope of line

c is the constant term

∵ Line y = m x + b , passes through point ( 1 , 5 ) having slope m = 3

So ,  5 = 3 × 1 + b

Or,   5 =  3 + b

∴  b = 5 - 3

I.e b = 2

So, The equation can be written as

y = 3 x + 2

Hence The value of b is 2  and The equation of line is y = 3 x + 2 .  Answer

Translate (3,2) to the left one unit. Then reflect the result over the y-axis. What are the coordinates of the final point?
OleMash [197]

Answer:

(-2, 2)

Step-by-step explanation:

Take point (3, 2) and first translate it left one unit.  Now the point is (2, 2)

Now reflect it over the y-axis.  Doing so keeps the y value the same, we have a vertical line of reflection, so we are only changing the distance to the y-axis, which is the x-value.  

Our x value is 2 units away from the y axis, so its reflection will be 2 units away on the other side of the axis.  

The new x value is -2, so the point is (-2, 2)
