The equation 5x+4y=20 represents a linear function in two variables. Identify the slope, x-intercept and y-intercept of this linear function

Here are the steps

put it into y=mx+b 4y=-5x+20

to isolate y divide both sides by y=-5/4+5

to find the xi

xi is when y=0 so plug it in to the equation 4y=-5x+20 4 (0) = - 5x+20

0=-5x+20 subtract 20 from each side - 20=-5x the negatives cancel out 20=5x

to isolate x divide each side by 5 x=20/5

20/5=4

Answers:

m=-5/4

yi=5

xi=4
