The slope is 4/949.'

Here's how I did it:

Explanation:

The formula for slope is ("change in y")/("change in x")change in ychange in x, or (y_2-y_1)/(x_2-x_1)y2−y1x2−x1.

Since we have the values of two points, (5, 9)(5,9) and (-4, 5)(−4,5), we can plug them into the formula and solve for the slope:
(5-9)/(-4-5)5−9−4−5

And now we simplify:
(-4)/(-9)−4−9

4/949

The slope is 4/949.

Hope this helps!

"slope "=4/9slope =49

Explanation:

"to calculate the slope m use the "color(blue)"gradient formula"to calculate the slope m use the gradient formula

•color(white)(x)m=(y_2-y_1)/(x_2-x_1)∙xm=y2−y1x2−x1

"let "(x_1,y_1)=(5,9)" and "(x_2,y_2)=(-4,5)let (x1,y1)=(5,9) and (x2,y2)=(−4,5)

rArrm=(5-9)/(-4-5)=(-4)/(-9)=4/9⇒m=5−9−4−5=−4−9=49
