Slope-intercept form: y = mx + b (m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y))
To find the slope(m), you can use the slope formula and plug in 2 points:
(x₁ , y₁) = (0, 2)
(x₂ , y₂) = (4, 5)
[slope is also 
"rise" is the number of units you go up(+ number) or down(negative number). "run" is the number of units you go to the right. If your slope for example is 2, you go up 2 units and to the right 1 unit. If your slope is -2, you go down 2 units and to the right 1 unit.]
^ you could just look at the graph and see how many units a point goes up or down and to the right to get to the next point (goes up 3, to the right 4)
To find b, plug in either of the 2 points into the equaation
(0,2)
2 = b
It will move 4 to the right horizontally
-45.6 is the answer if you evaluate
Answer:
605 rupees
Step-by-step explanation:
add the parts of the ratio 3 + 4 = 7
divide the number of notes by 7 to find one part of the ratio
= 11 ← 1 part of the ratio
3 parts = 3 × 11 = 33 ← number of 5 rupee notes
4 parts = 4 × 11 = 44 ← number of 10 rupee notes
Amount of money = (33 × 5 ) + (44 × 10) = 165 + 440 = 605 rupees
Hello,
To find the Unit Price of the loaves of bread just divide the cost by the amount of loaves it costed.
5.94 / 3 = $1.98
Each loaf (Unit Price) costs $1.98!
