Answer:
See below
Step-by-step explanation:
Slope intercept form is
- y = mx + b, where m= slope, b= y-intercept
Questions
Slope= -3 passes through point (15, -50)
-
y = -3x + b
- -50 = -3(15) + b ⇒ b = -50 + 45 ⇒ b = -5
- y = -3x - 5
Slope = 1/2 with and x-intercept of (28,0)
-
y = 1/2x + b
- 0 = 1/2*28 + b ⇒ b = 0 - 14 ⇒ b = -14
- y = 1/2x - 14
Slope = 7 passes through (1,2)
- y = 7x + b
- 2 = 1(7) + b ⇒ b = 2 - 7 ⇒ b = -5
- y = 7x - 5
Slope = -4 passes through (-2,5)
- y = -4x + b
- 5 = -2(-4) + b ⇒ b = 5 - 8 ⇒ b = -3
- y = -4x - 3
Slope = -2 with x-intercept of (-3,0)
- y = -2x + b
- 0 = -3(-2) + b ⇒ b = 0 - 6 ⇒ b = -6
- y = -2x - 6
Slope = 34 passes through the origin
- y = 34x, no y-intercept as the line passes through the origin
