Answer:
1) y = 5x + 100
2) y = -10x + 375
Step-by-step explanation:
The slope intercept form of an equation is expressed as y = mx+c
m is the slope
c is the intercept
1) Using the coordinate points (0,100) and (1, 105)
slope m = 105-100/1-0
m = 5/1
m = 5
Substitute m = 5 and (0,100) into the formula y = mx+c
100 = 5(0)+c
100 = 0 + c
c = 100
The required equation is y = 5x + 100
2) Using the coordinate points (0,375) and (5 325)
slope m = 325-375/5-0
m = -50/5
m = -10
Substitute m = -10 and (0,375) into the formula y = mx+c
375 = -10(0)+c
375 = 0 + c
c = 375
The required equation is y = -10x + 375
