She forgot/miscalculated the y-intercept (b)

Step-by-step explanation:

the actual equation is y=0.5x-6

first, I found the slope. y2-y1 / x2-x1 (0.5)

then I substituted in a point

then found the y-intercept (-6)

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
