Passing through (1,9),slope=2
2 answers:
Passes through (1, 9) with a slope of 2.
Assuming that we want this in slope intercept form, which is y=mx+b (m=slope, b=y-intercept) then we need to find the y-intercept! :)
To find the y-intercept (or b!!) you simply need to plug everything into slope intercept form using our given points.
y = mx + b
Plug everything in.
9 = 2(1) + b
Simplify.
9 = 2 + b
Subtract 2 from both sides.
9 - 2 = b
b = 7
Therefore, our y-intercept is 7! :)
Now that we have both the y-intercept and the slope, we can finally plug this into a new equation, using slope intercept form.
y = mx + b
y = 2x + 7
~Hope I helped!~
y = ax + bHere the slope is 2.
Then,
y = 2x + bThe line is passing through (1;9).
We just have to substitute that in the equation.
9 = 2*1+ bb = 9 - 2 b = 7That's the intercept.
Eventually, the equation is :
y = 2x + 7
Hope this helps !

Answer: He earns $169 after 13 hours
Step-by-step explanation:
To solve this we need to find out how much he earns per hour.
This can be identified using simply division.
130/10=13
He earns $13 per hour.
Now we multiply 13*13=169
He earns $169 after 13 hours
Answer:
10 and 7 are the numbers
Step-by-step explanation:
Let the number be x and y, ATQ, x+y=17 and x-y=3, solving it we will get x=10 and y=7
