We translate the data of Mary as (15,90) and (8, 62). In this case, the slope is (90-62) / (15-8) or equal to 4. The equation is y-y1 = m (x-x1) where m is the slope. Substituting, y - 90 = 4 (x-15) or equal to y = 4x + 30. <span> Lisa receives half the base amount that Mary does, but she is paid twice as much per student so the equation that of Lisa is y = 8x + 15.
when x is 20
</span><span>Mary : y = 4*20 + 30 =110
</span>Lisa : y =<span> 8*20 + 15 = 175.
Hence Lisa earns more.</span>
Answer:
4/9 x 3/8 = 1/6
Step-by-step explanation:
Answer:
plug in those values into y = mx +b
m = the slope
b= y-intercept
the equation of the line is:
y = 1/5x +10
