Question

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

Answer 1

The slope would be 2

Answer 2

Answer:

slope is -2

and y-intercept is 13

Step-by-step explanation:

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