Answer:

l = 9/2 or 4.5

m = 11/4 or 2.75

Step-by-step explanation:

4l + 8m = 40

8m = 40 - 4I

m = 5 - 0.5l

5l + 2m = 28

5l + 2(5 - 0.5l) = 28

5l + (10 - l) = 28

4l + 10 = 28

4l = 18

l = 18/4 or 9/2

l = 4.5

4l + 8m = 40

4(4.5) + 8m = 40

18 + 8m = 40

8m + 18 = 40

8m = 22

m = 22/8

m = 2.75

Wright an equation in slope-intercept (y=Mx+b) form for each line.
uysha [10]

Answer:

y = \frac{3}{5}x + 2

Step-by-step explanation:

Find slope (m) using two points (0, 2) and (5, 5):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{5 - 0} = \frac{3}{5}

y-intercept (b) = 2 (i.e the value of y when x = 0)

Substitute m = ⅗ and b = 2 in y = mx + b

The equation of the line would be:

✅y = \frac{3}{5}x + 2
