Y = 7x + 3
Find the x and y intercepts of the line

The x-intercept of the line is

The y-intercept of the line is 3

Step-by-step explanation:

If the equation of a line is y = m x + b, then

Let us use these facts to solve the question

∵ y = 7x + 3

→ Substitute y by 0 to find the x-intercept

∵ y = 0

∴ 0 = 7x + 3

→ Subtract 3 from both sides

∵ 0 - 3 = 7x + 3 - 3

∴ -3 = 7x

→ Divide both sides by 7 to find x

∵ =

∴ = x

∴ The x-intercept of the line is  

∵ y = 7x + 3

→ Substitute x by 0 to find the y-intercept

∵ x = 0

∴ y = 7(0) + 3

∴ y = 0 + 3

∴ y = 3

∴ The y-intercept of the line is 3

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
