Question

Find the equation of theline passing through (1,7)and having slope 2 units.​

Answer 1

Answer:

Hence, the equation of the line passing through (1, 7) and having slope of 2 units is y-2x = 5.

Step-by-step explanation:

point (1,7)

slope (m) = 2

equation :

y=mx+b, where m is the slope, b is the intercept.

You are given that the slope is 2, therefore m=2

So you have:

y=2x+b;

You need to find b. You also know that the line passes through the point (1,7). It means that if you plug in 7 for y and 1 for x, you shall obtain correct equality.

That is,

7=2*(1)+b shall be correct. Or

7=2+b.

b= 5

So b= 5 Therefore, your line equation in the slope-intercept form looks as follows:

y=2x+5
