(-10, -10) and (-2, -3) find the slope.
ankoles [38]
The slope is 7/8.

Slope formula is the change in y over the change in x,
M=y2-y1 / x2-x1

M= -3 - (-10) / -2 - (-10)

Remember that two negatives equal a positive.

That makes the equation:
M= -3 + 10 / -2 + 10

M= 7/8

Please help me is this statement true or false 3(36 - 11) = 45?
viva [34]
Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
3(36 - 11) =
3 \times 36 - 3 \times 11  =
108 - 33 =
75

75 does not equal 45 and therefore the statement is false.

The table shows the cost of hiring a concrete mixer for up to 5 days.
givi [52]

Answer:

i. daily charge = £13

ii. fixed charge = £6

Step-by-step explanation:

Number of days (x) | Cost in £ (y)

1 | 19

2 | 32

3 | 45

4 | 58

5 | 71

Using the given table, we can represent this situation with an equation in slope-intercept form, y = mx + b, where,

m = slope = daily charge

b = y-intercept = fixed charge

✔️Thus, using the coordinates of any two given pairs, say (1, 19) and (2, 32):

Slope (m) = ∆y/∆x = (32 - 19)/(2 - 1) = 13/1

Slope (m) = 13

Therefore daily charge = £13

✔️To find y-intercept (b), substitute (x, y) = (1, 19) and m = 13 into y = mx + b.

Thus:

19 = (13)(1) + b

19 = 13 + b

b = 19 - 13

b = 6

Therefore, fixed charge = £6

✔️Substitute m = 13 and b = 6 into y = mx + b to represent the function given for the situation:

y = 13x + 6
