What is the equation for the line that passes through (0,-9) and has a slope equal to 5?

y=5x-9

Step-by-step explanation:

Equation of line in slope-intercept form is:

y=mx+c where m denotes slope of line and c denotes y-intercept.

y-intercept is a point on the line where value of x is zero.

Slope is defined as steepness of a line and also called gradient.It is denoted by m.

From question statement ,we observe that

slope=m= 5

y-intercept at (0,-9) which means c=-9.

Putting the value of slope and y-intercept in slope-intercept form,we get

y=(5)x+(-9)

y=5x-9 is equation of line that passes through (0,-9) and has a slope equal to 5.
