Answer:
option a)
y = m(0.5) + 1.8
Step-by-step explanation:
Equation
<h3>
y = mx + c</h3>
represent the equation of straight line
here m = gradient of straight line
c = y-intercept
First find the gradient of the graph
<h3>
m = y2 - y1 / x2 - x1</h3>
= 4 - 3 / 4 - 2
= 1 / 2
Put the values in the equation of straight line
y =mx + c
4 = 1/2(4) + c
c = 2
y = 1/2x + 2
which is approximately equal to y = 0.5x + 1.8
First you make -1 3/5 into an improper fraction, -8/5
Since you're dividing a fraction by another fraction you'd change it to -8/5 × -3/2
(Don't forget to flip -2/3 to -3/2)
when you multiply it it'd be 24/10
(It is a positive number because when you multiply two negative numbers it becomes positive)
24/10 as a mixed fraction is 2 1/5
