If the slope of a line is 2 and passes through (2, 5), what is the function of the line?

y = 2x + 1

Step-by-step explanation:

As we know, the slop formula is

So, if we substitute the slope into this,

Now if we substitute x and y from the point (2,5) into this,

Hence, when we substitute c,

y = 2x+1

false

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
