Answer:
y = - 8x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 8 and (0, 3) → c = 3
y = - 8x + 3 ← equation of line
See how if the number (1-4 u would round down, 5-9 u round up) u would look at the place value it asks then look at the one next to it and see if u round up of down so it would be 17.3
Answer:
275.
Step-by-step explanation:
The gradient of the graph is 70/2 = 35 and it passes through the origin so we can write its equation as
y = 35x.
The gradient of the function represented by the the table is
(240-180) / (4-3) = 60
Ehen x = 3 y = 180 so when x = 0 y = 180 - 60 - 60 - 60 = 0 and the equation of this function is
y = 60x.
For the first equation when x = 11, y = 35*11 = 385.
For the second it is 60 * 11 = 660
So our answer is 660 - 385
= 275
