Explanation:
A line parallel to the y-axis would have the same slope, and the slope of the y-axis is zero.
If the slope is zero and the line passes through the point (-10,-7), the y-intercept for the line is -7.
y = mx + b
y = 0x - 7
(zero x is just zero, so:)
y = -7

Rational numbers include fractions and decimals that end or have a pattern. Irrational numbers, however, do not end and have an arbitrary pattern. -0.25 is rational because it is a terminating decimal which means it ends.
Examples of irrational numbers include:
√2 , -√101 , π (pi)
Examples of rational numbers include:
-0.89 , √16 , 1/3

The equation of line will be;
⇒ y = - 3/5x + 3
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.
Now,
Since, James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.
Hence, The slope of the line = - 3/5
And, The y - intercept = 3
Thus, The equation of line will be;
⇒ y = - 3/5x + 3
