Question

Find the slope and y-intercept of (5,3) and (4,5)

Answer 1

The slope would be 2

Answer 2

slope is -2

and y-intercept is 13

Explanation:

`slope=m=(y_2-y_1)/(x_2-x_1) \\m=(5-3)/(4-5)=(2)/(-1)\\slope=m= -2\\Then, we can write equation of line as y=mx+b\\y=-2x+b\\using either points given we can find b \\so using point (4,5)\\5=-2(4)+b\\so b=13\\ therefore y-intercept is = 13`
