CAN U PLS HELP

Answer 1

Answer:

Step-by-step explanation:

Given the algebraic equation of a line, we are able to graph it in a number of ways. In this section, we will be given a geometric description of a line and be asked to find the algebraic equation. Finding the equation of a line can be accomplished in a number of ways, the first of which makes use of slope-intercept form,  

y

=

m

x

+

b

. If we know the slope, m, and the y-intercept, (0, b), we can construct the equation.

 

Example 1: Find the equation of a line with slope  

m

=

−

5

8

and y-intercept (0, 1).

Solution: The given y-intercept implies that  

b

=

1

. Substitute the slope m and the y-value of the y-intercept b into the equation  

y

=

m

x

b

.

Answer:  

y

=
