Hello!
So to find the y-coordinate we need an equation for the line. The equation we can use is
y = mx + b
In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.
10 = 3(0) + b
10 = 0 + b
10 = b
So now that we've found b, we can use this in our equation
y = 4x + b
So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.
y = 4(2) + 10
y = 8 + 10
y = 18
18 is your y-coordinate
Honestly idk this question I just need to do this to ask questions :(
Answer:
Y= X - 31.5
Step-by-step explanation:
find the gradient then the equation
Answer:
(3/5, 9/5)
Step-by-step explanation:
Here's the graph :)
This equation is in y = mx + b format, which means m is the slope.
y = 7x + 4
m = 7
The slope is 7
