Answer:
y = -2.5 x + 6.5
Step-by-step explanation:
The equation of a line in slope-intercept form is written as
y = mx + b where m is the slope and b is the y-intercept.
a) We can find the slope of the line passing through (-1,30 and (-4, 5) by subtracting the y coordinates and dividing the difference by the difference if the x coordinates:
m = (5 - 3 ) = 2
-4 - (-1) -3
Now use this slope and substitute the coordinates of either of the given points to find the y-intercept, b . Let's use (-1,3):
y = mx + b
3 = -2 • -1 + b
3
3= 2 + b
3
7 = b
3
The equation of the line will be y = -2 x + 7
3 3
b) Using y = mx + b, we can substitute -2.5 for the slope and use the point to find the y-intercept:
y = -2.5x + b
1.5 = -2.5 • 2 + b
1.5 = -5 + b
6.5 = b
The equation of the line will be:
y = -2.5 x + 6.5

Step-by-step explanation:
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
Answer:
it’s c trust me
Step-by-step explanation:
if it rotates 180 clockwise, cross D and b out.
B is only a 90 rotation
A is Wong because u only dialatwd
So c is correct
Given:
1 of 3 pasta meals
1 of 7 chicken meals
1 of 3 fish meals
Simply multiply the total number of choices:
3 x 7 x 3 = 63
Ping can choose a dinner meal in 63 ways.
