Answer:
9.1 = a+4
Step-by-step explanation:
The right side has two different values, variable <em>a,</em> constant 4.
The left side has the constant 9.1.
If both sides are equal, then
a + 4 should equal 9.1
Answer:
y = x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = , hence
y = x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y = x + 7 ← equation in slope-intercept form
