A line with a slope of 4 passes through the point (2, 1 ). What is the equation of this line?

Put this in y= mx +b form

we have the slope(4) as well as a set of points for x and y so we have everything we need to solve for b

1= 4(2) + b

1 =8+b   B=-7

so equation is y = 4x -7

Step-by-step explanation: can i get brainley? :)

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
